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

We purchased a 2002 Toyota Avalon from College Cars Chicago on 6/10/2020 after our other 2002 Toyota Avalon was totaled. Exact year, make, and model both cars were well maintained and taken care of. We were planning on driving the car we had for many more years until the accident. I got on the internet the very next day and more or less stumbled on finding one we purchased from Zack that was in excellent condition. Unfortunately, things can go wrong with any car even if they are well maintained. We experienced the airbag light would not go out and it was determined that the SRS computer had to be replaced. This was not like replacing a lightbulb. Zack stood behind College Cars 30 day 1000 mile warranty and worked with myself and the dealer making the repair as painless as possible. Very professional and customer-oriented. Would definitely return if and when we needed or wanted another vehicle. Also will highly recommend to anyone. We live in Indiana but it was well worth the approximate two-hour drive. Thanks again Zack!

I bought this car used in 2012. Over 10yrs later and 214k miles she still rolling. I did have to replace power steering sensor last year and unfortunately it has to be reprogrammed in shop or would of saved chuck of money. My evap solenoid is giving me trouble but my heat my AC my radio my windows all work and I would buy a brand new one if I good. Lots of replaced headlamp bulbs over the years but once rewired it made much better

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!

2002 was the end of the line for performance cars at Pontiac. The Firebird and Trans Am were iconic muscle cars that helped define the genre. I was lucky in finding 1 of 2000 Collector Edition models with super low miles. The car runs strong, handles well, and still looks great 19 years later. The interior is dated but nobody buys a Trans Am for the interior. It is still fast and fun to drive. Getting a 4th generation Firebird is more economical then buying a project and restoring/modifying it to meet modern standards. This car is for serious drivers to are tired of the current run of the mill cookie-cutter tin can cars today, and it is half the price of current muscle car remnants, it can still keep up with most of them too!

Amar was extremely thorough and efficient in explaining every aspect of the car and its features, as well as all the details related to the purchase process. He was very helpful, patient, and a true pleasure to deal with.

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!

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.

Great service from Zamar, he was extremely helpful, polite, cheerful, and professional. Nothing was too much trouble, and the whole team was very supportive. I would certainly recommend them.

(owner of three 06/07 g6 GT/GTPs convertibles) Wonderful, sporty look. Design is great with minimal flaws such as cover that opens when top comes down malfunctioning or air vents coming out. Seats look great but sit in this car longer then two hours you'll wish you weren't. Every car I've seen has a rip in driver seat, you'll know what I mean if you own one most likely. Engine and transmission are strong and reliable with little maintenance needed. Things like CV joints, ball joints, sway bars, etc you'll need to replace often along with many electrical details and oil/tranny leaks. All around amazing, going on five years with my first one from 132k miles to 203k miles it runs just as it did the day I bought it.

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.

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

The purchasing process was handled efficiently and professionally. I appreciated the sales executive’s patience, strong knowledge, and courteous approach throughout. Very happy overall 🤩 Thank you

Have had this car over 2 years never had anything major wrong with it at all! Starts up every single time and at 250k plus miles she is stil rolling with no issues!!! Love, Love LOVE!

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 😊

I have always wanted one. Now that I have it I am not disappointed. Pontiac knows how to make excitement. The Red leather in my car is just beautiful and the seats are the best ever. Performance is off the chain with this thing, stomp the pedal and the thing almost jumps off the road. It will be a keeper!

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.

As a daily driver this car has everything needed to get there while having fun. Power is exciting and handling excellent. I Love this car.

I am beyond pleased and impressed with this dealership. Working with Rami and his team was easy, efficient, and professional. I used my own credit union for my financing and even they said what a pleasure it was working with Rami and Diamond and just how thorough and on top of things they were. I had never shipped a car out of state before and this was also my first Porsche and I’m sure I wasn’t the easiest to deal with at times, not on purpose of course, but just because it was such a new experience. I felt very taken care of and accommodated with everything I needed. Great communication and very fair. I can’t say enough good things! Very very happy and this dealer is top notch with quality of cars also - immaculate cars and care of them. My transport company even commented how nice this dealership is. We will be back for sure ! Thank you!!!

Miles and was going strong

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.

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

Great experience! Fast shipping. Communication was quick. Transaction could NOT have been easier! 100% will use them again.

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.

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 have driven/ridden in this car; fantastic performance, hold onto your seat when you pop the clutch.

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?

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.

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.

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.

Karl and Moe at Moto Zone were fantastic to deal with ..the Accord was well advertised by pictures and descriptions and the delivery was flawless..not having seen the car because of the distance between us when the car arrived it was exactly as depicted by Moe and Karl mechanically it is perfect and body wise extremely great looking for a 2012 with only 49,000 mls…thank you again Karl Moe and Moto Zone…mark

Bought this car at a junk auction. It was in poor shape but I knew that going into it. It was a jewel of a find 06 gtp. It's my fun summer's only, occasional driver. I gutted all the seats and replaced them with leather as well as fixed the interior. Car had lots of mechanical issues as well but the engine was and still is strong. Its a fun car to buy and take under your wing as a collectors, project car. Lots of cheap parts in the junk yards now. I would not recommend this car for a daily driver unless you plan on spending a lot of money fixing stuff. The cars are old.
