Used Pontiac cars for sale near Markham, IL under $4,000,000

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’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

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 love the interior of it as well as the exterior,it's an all around great car. It gets great gas mileage and the supercharger whine is nice.

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

(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.

Very good people easy to work with willing to work with you great customer service and fast not in there all day! I’ll be buying from here!!!

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

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 a great experience with car shopping with Kendall Maxey, he had great knowledge with the whole process. I would highly recommend Castle Chevy to others!

16 year old car; I didn't put a ton of miles on it, had the remote start. I live this car and still drive it. I'm tall and needed to be able to sit comfortably and upright (have spinal stenosis). Loved the remote start so much. It's my zip zip around car. Longer wheelbase made it a little harder to park in those tiny parking spaces at strip malls. Enjoyed immensely taking this car in day trips and weekend get aways. Fam still borrow it for trips. So much room for the passengers, never complaints from passengers. Lots of room to pack what you need. I've had to replace a wheel bearing. The paint is chopping off now {it sits outside in all weather}. The chrome plated wheels started peeling fairly early on but didn't bother me much. They do now have to be sanded when getting new tires to ensure proper seal (they do that at the tire installation shop) otherwise you have a slow leak. I now have to manually turn off the blinkers, but cld pay to have that fixed, just haven't. Speakers still make me happy. I can plug in a phone and listen to my music, but of course too old for a screen or other conveniences. I love my torrent will be sad when it it done and gone.

Everything went perfectly. The car ran smoothly, and I was very happy with the process. It was quick, easy, and completely hassle-free. Overall, a flawless experience. Highly satisfied..

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.

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

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 bought my 1991 firebird last summer. I only had to fix the alternator when i bought it but i have not had any troubles after that day. The car itself is so low to the ground it allows for fun driving, and can handle sharp turns. has great torque and horse power to start with i have had no need to tweek any thing. I would like to say this car is fine for getting around form work or driving people around, but if you are looking for a car with a kick and that you can have fun with this is the car.I personally feel at home driving though a local car town and it fits in with the older classics. with the bright red paint job. overall best car i have seen all around. but from being in Minnesota the car struggles in winter without winter tires.

Very friendly and helpful service. They had no problem letting me take the car I was looking at to a shop to get inspected. Had Carfax available and even sent me home with a copy of it. Glad we were able to make a deal, Nick!

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.

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.

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.

I own a 2001 Pontiac Grand Prix GTP.I got the car in excellent exterior condition,in 2020, considering that it was20 years old. The old engine has never let me down (unless you consider listing to audio for four hours and draining the battery). Its interior needed a bit of tlc when I got it,and so far I’ve put around 30,000 miles on it. But power? Ahhh,yes. And currently making 25.2 miles per gallon. Longest trip I ever took it on was 13 hours straight through, talk about comfort. It also hit,subdued and recovered from a deer as well.😏 I then fixed it,and am still using it today. It’s a perfect car for someone introduced to the Grand Prix,but wanting to upgrade from a GT. The only downside is that,because of their age and lack of care in their younger days,these cars are getting increasingly hard to find in nice shape. Most of them are rusted out and banged up like tin cans. So if you’re shopping around,look for a GTP with as little rust as possible,sit back and let the adventure begin!

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.

Al was very helpful, professional and he made the process seamless. The entire experience was amazing.

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.

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.

The service advisor was very polite and helpful. The dealership is very clean. The advisor keeps the customer updated on the services the car is receiving in the service area.

I have driven two firebirds, a 3800 v6 and a LT1 v8, both cars were great. The only complaints are in the interior, being an older car the plastic doesn’t hold up well. The 3800 v6 is the best engine ever made for a daily driver, absolutely reliable and almost impossible to blow up. I do some hard driving in my completely stock v6 and it has lasted extremely well. The v6 also has plenty of power, I even beat a friend in a v8 challenger in a drag race once, though he was not a very good driver.

I purchased a used car a 2017 Toyota Corolla for my daughter for a very good price. They have great reasonable prices.

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.

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!!!

Love the car, its a joy to drive. Love that it tells you that you have driven two hours and you should stop and rest.

Bought a Tacoma from with them and Jared was very professional and super helpful. Great experience for a first time buyer. Highly recommend!

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.
