Used Pontiac coupes for sale near Oak Brook, IL

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!

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

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!

Great looking car fun car to drive, great speed, a car you can drive and get a thumbs up from people you do not know. The Formula was only made in 1988 and the suspension was a new suspension for that year. all other fiero's suspensions were from a Chevy citation

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 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.

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.

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.

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

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.

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

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

The vehicle has been in my family for 20 years. Past down from father to now daughter (myself). I am now over 50 yrs old and would like a luxury vehicle and have had many years of t-tops off with the wind blowing with my friends going to softball games, etc. it's now time to hand it off to a younger girl/guy who could enjoy like I did. :)

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.

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 have owned my GTO for about 17 years. The car is true to the name and is a great grand touring car. I have driven it all over the country. It is about to cross the 250,000 mile mark. No real major issues. It is rough, but still going just fine. I plan on rebuilding it.

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!!!

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.

Dennis Bedka is AMAZING. Got an amazing car with the best customer service.Had specific needs and they were met. Financing part, he explained things very well & answered all of our questions. Patient and very professional! Thank you Dennis!

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.

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?

In completed this car will be an eye catcher. It has won trophy's at car shows in the past. The engine is a 383 with all forged components.

Great company to a car from buy from. Honest, responsive . Great team, Thank you mike.

Second owner of 1970 GTO Judge. Manual steering and manual brakes make for a handful, but straightline is definitely a gas! Everyone watches and talks about how they wished they would have kept the great one from their past. Inefficient, uncomfortable and a task to drive but will not trade for anything.

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.

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'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

All around amazing experience at the Auto Showcase of Carol Stream Car Dealership, great people, great selection and even better prices!

I bought mine new in January 2006 after I totaled my 1999 BMW Dinan M3. The GTO is simply an amazing performer. The only mod on it is a K&N cold air intake, which actually added a little spunk to it. It revved up quicker and got an extra mile or so to the gallon. I bought a second used 2006 GTO in 2012. It had an aftermarket cat back exhaust system on it and the sound was definitely worth it. Stock, they were identical cars. At the time my husband and I ran them head to head. I was in the one I bought new, which had 40k miles on it and he was in the used one, with 68k miles. I got him through 1st and 2nd gear and he couldn’t make up the difference. My only complaint was the front suspension was set up weird and the front passenger tire rubbed on the spring. It was a fairly common complaint but Pontiac was done making them and refused to correct the issue. We were able to adjust it ourselves and take care of the problem. There was one issue with the climate control electronics but the dealer repaired it. The cars were designed to be put to the test and they held up reasonably well. The used one had to have the top end of the LS2 rebuilt at 70k miles, consequently the bottom end started making noise at about 75k miles, so I sold it. The first one needed a slave cylinder at 44k miles. I I’ve never regretted buying either of them. The interior is a far cry from the M3, but the performance of the LS2 would have left the Bimmer in the dust. In 2006, only 13948 were produced in 7 colors. 63% came with the Tremec 6 sp the other 37% were automatics. They have held their value due to the low production numbers. 15740 were produced in 2004 and 11069 in 2005. If you ever see a 2004 Purple Cosmos GTO, buy it! There were only 700 produced before that color was removed from the lineup.

Quick response to my inquiry. However, I specified that I wanted a car with an automatic shift and no convertibles, but they continued to send me information on cars with a manual shift and convertibles.

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.
