Used Pontiac cars for sale near Posen, IL

Easy transaction with excellent two-way communication. The car was exactly as described (no surprises). Since it was an in-state transaction, the Diamond team made it super easy: the car was delivered with new plates and tags. All I have to do is wait for the title to arrive from the state. There was zero pressure to buy the car or hurry up the transaction. Tyler took the time to point out the few flaws in the car such that I wasn't surprised upon delivery. I would not hesitate to buy another car from Diamond Motorworks.

I’ve owned mine since 2007 bought it off the lot love my GOAT when I take people for a ride first thing said is do you want to sell it of course the answer is no never let me down I noticed after the GOAT came out other car companies started following the style once you drive one you’ll want one

I was very impressed at the condition of the cars in this expansive indoor showroom filled mostly with classic cars. Owner is very knowledgeable about all the cars on his lot but is also transparent on any issues they may have ane what it may take to fix it. I would not hesitate to purchase from here!

So September 20th 2025 I finally bought my dream car 2005 gto impulse blue with the blue seats with only 28500 miles on it. It has a stage 2 cam 243 ported heads long tube headers full cat back bora exhaust, ported throttle body, drag bags 18inch after market rims and brand new tires voolant cool intake 220 degrees thermostat. Its so freaking fast like 4 real the recipe for work was 10k thats without rims and tires. Its basically 500 hp I live in Chicago and had it shipped from Oregon. No rust even on under carriage paid $23500 out right 2k to ship and $2200 for tax title and plates so total $27500. I wouldn't take it back for nothing! It holds its valve very well and will only go up. Its not my daily driver either just my fun car i use when I want just not in the snow lol.

Ive owned a FWD 2006 pontiac vibe for 12 years , its run flawless ( standard battery and belts replaced ) its THE most RELIABLE car Ive ever owned in 55 years of owning cars!!! ( had about 7 cars in those years ) its rugged, drives well and semi comfortable .. visibility is tops and the hatch back room is great ! Best of all this car Never Dies ...current mileage is 278,000 miles runs great

I was shopping for my first car and with the amazing help of this customer service I found the perfect Jeep Wrangler for me for a great price. They were extremely helpful and understanding! Car shopping here from now on.

One of just 1,591 HO-equipped GTO Convertibles produced in 1967, this car features a long list of coveted factory options that include an upgrade to Ram Air set up, power steering, power-assisted front disc brakes, power convertible top working 8 Track Tape Player and a 3.90:1 Safe-T-Track Posi-traction rear end. Only 1.9 percent of the total 1967 GTO production run were allocated to HO-equipped convertibles, making this car extremely rare. This Pontiac GTO presents beautifully in its Red finish with a black convertible top, highlighted by a set of Rally II rims. The interior is classic GTO with black vinyl upholstery, wood-grain dashboard, Rally gauges with a tachometer, sport steering wheel and factory-issue seat belts, both front and rear. This particular GTO is a low-production example with all of the right equipment, making this a very desirable, high-performance classic. The Rebuild and Balance of this HO 9786133 WS motor was performed by a professional engine build speed shop to provide peak performance with long engine life. The rebuild included re-work of the 670 heads, 72cc chambers with a fresh 3 angle competition valve job, resurfacing of deck, new Viton positive valve seals and new hardened exhaust seats. The 9786133 WS motor was fitted with a new complete Stroker Rotating assembly from Butler Performance with dished Forged Piston to provide 9.75:1 compression with the 72cc #670 cylinder heads fitted with a COMP Ram Air IV Cam, Scorpion Raving 1052 Roller Rocker Arms, 4 barrel Quadra-Jet with a RAM AIR configuration sitting on top of the original 9786286 intake manifold with Power Coated HO D Port Exhaust Manifolds in place for connection to the new 2.5” PYPES no X- pipe SS exhaust system, running on pump gas 92-93 octane.

bought used with 128xxx. 6 years later still wouldn't sell. I have yet to get into a situation that I wasn't able to maneuver it out of easily. taken it through spots that trucks couldn't (driver experience and ability). for the last year it has served as one of the best work trucks I've ever been around. I know on more than a few times that it was definitely overloaded I'm talking about the rear fender being about 1/2 Inch from the tire, and she hasn't disappointed me yet or let me down. only reason why I didn't give 5 stars all the way across the board, is that horrible evil things called governors at 108mph. it's now over 21 years old and 180xxxish miles. only thing I have upgraded is the air intake and filter. (BEFORE) if you floor in from a dead stop it would shift into 2ND gear at 45MPH (AFTER) 50MPH. (BEFORE) from 2nd to 3rd a 90MPH, (AFTER) AROUND 100MPH

This car is great, its comfortable, fast, and the V8 Can get up and go. However, compared to more modern cars, the Poniac 2006 GXP V8 shows its age, My car cant accelerate as quickly as more modern cars. But its still a solid car. The most major issue with the GXP is the tires and suspension. This car is apparantly designed to drive on Perfectly Smooth roads. Which is great if you live in a Gated Community somehwere houses are $500,000 each and everybody is perfectly blonde. However, I prefer more 'All-Terrain' vehicles compared to 'high-preformance but extremely delicate.' I'll compare the 2 cars I've owned: Jeep 1996 Grand Cherokoo Laredo Extremely Tough, can go anywhere, I can drive over curbs easily. Poniac 2006 Is more like Princess and the Pea. If I hit a Gravel Rock, the whole car will feel it. The Jeep, can go anywhere on Earth basically. The Poniac, Hit a Curb? Need a New Rim, the whole cars missaligned and tires need rebalanced, and now the Tires going flat. Hit a pothole in the Jeep, no problem, keep driving. In the Poniac, Now everything needs re-alligned, rim is damaged, etc. Just as an example. ^ The Poniac is reliable, its just extremely sensitive and needs perfect roads. The Jeep is all-terrain, durable, and strong. I'd drive my Jeep anyday if I could. Considered I got my Jeep for $5k, then put $5k in upgrades/repairs, Id get it again anyday. The Poniac was $32k new, and is just extremely sensative.

Real curtious and knowledgeable staff I would tell my friends and family about this car lot

My 2008 G8GT has 185K on it and it still drives and handles like a new car. I have changed the brakes to slotted and change the oil myself every 3-4k miles. Front seats are not that comfortable for long trips and is my only minor complaint. I will keep the car as long as I can because there is nothing like the power being offered in a four door by an American Car Company.

Diamond Motorworks is truly a hidden gem! Rami and his team made the entire buying process an absolute pleasure! Their showroom is gorgeous and their selection of high end inventory is second to none! Thanks so much for making the first of many of my dreams come true 😊

Loved my firebirds . I bought a new 1994 and a 1999 . V6 but awesome power it’s a Pontiac I replaced window motors , antenna motor, alternator, rotar,flip light motor ,oil gastric seals , I sold it and regretted it , but I figured I was grown up in my late 30’s but boy am I looking for the last one made miss my car , fun to drive and it got so many compliments black no tee tops no ram hood but beautiful I’ve noticed people haven’t taken care of theirs in the used one’s I’m looking for , how sad wish Pontiac would make them again beautiful styling cars , it had 210,000. Miles and was going strong

Great customer service. I bought a Toyota Sequoia and it was a great find. Haven’t had any issues with the car and drives smooth. This was a bargain gem!

So ...the grand am .....what can I say ...it’s never broken on me and replacement parts are very cheap .its a 01”grand am se1 ,typical automatic,a bit cheesy of a interior like it took some ideas from fast and furious back then but certainly has many building potential opportunities,so all in all if you want some thing cheap and very much could last quite a long time in the right hands the I suggest getting this car (and I payed 550 $ for mine and again hasn’t broken since I bought it

I recently sold my 2014 Corvette Z51 to Diamond Motorwork, and the experience was outstanding from start to finish. I worked with Luke, who was incredibly kind, patient, and professional. He made the entire process seamless — even going out of his way to meet me at my workplace to pick up the car and finalize paperwork. His flexibility and attention to detail made it easy to choose Diamond over other offers. The price was fair, their reputation solid, and they took the time to ensure I was comfortable with every step. I especially appreciated how Luke worked around my schedule and kept everything stress-free. The owner, Rami, was also very attentive. While Luke handled things so smoothly that Rami didn’t need to step in much, he was present and supportive throughout — especially when I requested a wire transfer instead of a check. That extra layer of reassurance gave me real peace of mind. If buying from Diamond is anything like selling to them, I’ll be stopping in there first when it’s time for my next car. Highly recommend Diamond Motorwork for anyone looking for a trustworthy, respectful, and hassle-free automotive experience.

I love driving my t top firebird runs great and still looks good.only 97,000 miles on a 1996 would buy a new one if they still made them.

Pete Fotops was great. Best car buying experience I have ever had. Answered all my questions, facilitated delivery and Camaro was exactly as advertised. This is a great dealership and Pete is true professional. Highly recommend, will buy from again!

I've always been a Pontiac conisur. In '77 I got a 69. Absolutely amazing. In 2003 I got a 91. Now I have a '95 and it is tops. Named her SAM for Surface to Air Missle. Yes I am retired Army. I recommend anyone who appreciates muscle cars to get one. Let's keep the legend of John Delorian's brilliance alive

I had a great experience with the team at Wild Bill’s Auto Sales & Parts from start to finish. Everyone was friendly, professional, and very knowledgeable. They took the time to explain everything clearly, answered all of my questions, and made sure I understood the entire process without ever making me feel rushed or pressured. The whole experience was smooth and well-organized, and it was clear they genuinely care about their customers. I really appreciated how transparent they were throughout the process. I have absolutely no complaints—everything went very well. I would definitely recommend Wild Bill’s Auto Sales & Parts to anyone looking for honest service and a great overall experience.

I’m a bragging past owner of a 2006 G6 Gypsy sedan. First owner up to around 37,000 miles. Great experience & performance! Only issue that aggravated me was the key release from the ignition “ which was repeatedly repaired & never solved?” My model was the rare 6 speed manual “ yes in a sedan!!!!” The manual had to be in a certain precise position to trigger the ignition key release. I joked with GM service department that apparently the car wanted to keep driving?! The only other service I can remember was the leather seat cover replaced because the color wore away. & a suspension part up front. Everything covered by factory no arguments. I’m extremely serious that this is one General Motors hidden past gems!!!! “ keep in mind I am NOT talking base entry level model here.” Everyone knows about the G8 the solstice which is understandably justified! However these G6 GTP & GXP are the best investment for the budget minded to get performance in a competitive fun driving sedan with luggage & storage space!” Unless you’re smart enough to purchase the HARDTOP metal roof convertible!” Do your self & your wallet a favor & don’t ignore the vehicle when looking!

Excellent service….. nice car with good condition and god price…Thank you Premier auto work….👍👌

I purchased my 2004 Pontiac Grand Prix in July 2008. At the time of the purchase it has 55,000 miles and today I have 346,000. The original motor and transmission is still in the car. I haven’t experienced any major mechanical issues.

Inquired when I located the car online. They responded in a timely manner and we set up an appt. Staff was very friendly. Price point and negotiations were very fair. No pressure sales. They handled all the paperwork, licensing and registration. The entire process was very easy.

This is a great muscle car! Probably too powerful for some, but it sure does have some scoot! We'll be sad to see it leave, but just don't have the time to keep the engine maintenance up.

Recently purchased a car from Wild Bill’s Auto Sales & Parts, and Amer was amazing throughout the entire process. He was always available, responded quickly to any questions, and was extremely informative. Amer gave clear, detailed instructions on the purchase process. Highly recommend—thanks, Amer

My 07 G5 GT has 219,000 miles. It has been a great car and it's still going strong. The last few years have been my most expensive yet but I guess that's to be expected with a car this old. Wheel bearings seem to be an issue but other than that, this car has held up very good and I'm not looking forward to having to replace it someday.

Very professional and easy to deal with. The salesman walked me through the whole deal. I would recommend this company if you’re looking for a good deal. MGM

I had this car for over 6 years and it was awesome. It got me through everything. It was very reliable and a very nice car.

I had been looking on cars.com for a car and when this one was listed, the color and condition were what I wanted. Because I live close to the dealer, I went and looked at the car in person. I was allowed to test drive the car by myself so I could evaluate it. Karim Zeidan was extremely friendly and helpful and his showroom is modern, clean and filled with great cars. The whole process was a pleasant experience.

I loved my 2000 Firebird! Make sure you get it with T-Tops! It was comfortable and had no major issues. Ran great and at that time I was sorry I had sold it.

i bought a 86 pontiac 2+2 . my credit union was not still in my state, so needed a co op credit union . they did not do that amount of money with out signed documents from my home credit union .mgm worked with me to get my payment worked through. it took a couple of weeks . when car got here there was a oversight with a maintenance issue .we talked back and forth we reached a agreement and they helped to fix the problem.in my case everything worked out

I had a 97 formula T-Top with the LT1, the stock mufflerwasn't all that but the Flowmaster was a compliment to the 5.7L 350 cubic inch V8.it road comfortably from the driver seat but the back seats you either had your knees up in your face or the front passenger seat all in your grill. You are driving one of the elite machines setting in the Pontiac cockpit. I enjoyed just starting that car the rumble and the roar when it fired and the humble rumble while crusin along and 70mph was it's sweet spot their wasn't a curve it couldn't handle at 70 just let off the gas and it would glide steady and that my friend is a different perspective of comfortable. I got several careless but doing 105 in a 50 got me a wreckless driving. But it's been nearly 30yrs and I still dream about that car I hope to get another one someday

Thomas was very nice. The sale of car and delivery of car went very well. Alondra was very helpful and kind with the paperwork transactions. I was very comfortable with the whole team! Great job?

Own and driven the 1992 EU build black color T-Top v6 from late 90's to 2003. If I could I still will drive it but I moved after 03 from Germany to Thailand and the car was standing all the time till 2010 without moving it. They are rare in Europe to get especially the last models from 1998 to 2002. With luck I get maybe once for a normal second hand price and not a collectors price one again, no matter v6 or v8 just the last model made till 2002. I saw prices today for v6 99' convertible by 12.800 EUR and a lot more for v8 engine WS6 starting at 16.000 EUR.

Today We Purchased a Tesla Y 3rd row option Long Range, which is awesome. Jim, I Could not be happier with the paperwork process and the loan Apr Rate. Thanks for the Charger which is a bonus.. I will definitely be back for my daughters car here soon.

Great little sport car head turning .Makes me fill 30 years younger .I can wait for spring and summer to come.Love to cruise with top down.Mine is 2007 with 33000 miles ,premium package and Pioner navigation system with camera.Love it
