Used Pontiac coupes for sale near Matteson, 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!

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 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!

After driving this car for 16 years it is time for my daughter to drive it for awhile maybe another 16 years.

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.

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.

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

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 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 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!

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

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.

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.

Back in 2005 I never thought I would purchase a $35,000 car, but the Pontiac GTO had everything I was looking for in a sporty car: Excellent styling, rear wheel drive, large powerful V8 engine, solid transmission, and a stiff suspension. I am SO glad I bought it when I did, rather than waiting for the "new" Camaro to debut. The Camaro was a HUGE disappointment, with its high belt-line (meaning much smaller windows that are too high to comfortably rest your arm on the window sill while driving!), poor visibility, and cheap interior plastics. In contrast, the GTO has large windows, very nice soft plastics in the interior and very nice suede fabric on the door panels. The seats provide excellent support. While the GTO is low to the ground (it IS a sport car, after all), it is not difficult to get into and out of as many sporty cars are. And you do not feel like you are sitting in a "bucket" that you need to climb out of, as is the case with most unibody constructed cars. The LS2 6.0L V8 engine is awesome, with plenty of power in reserve at all times. Yes, premium fuel is recommended, but at least the engine has no gimmicks like a turbo that needs to be cooled down after you stop, before you turn the engine off! The automatic transmission is also a very strong 4-speed (including overdrive) model, rather than those newer 6-, 7-, and 8-speed automatics that cannot decide what gear to be in when you are trying to accelerate quickly or climb the mountains! The steering and suspension are very tight, with no play whatsoever. Problems? The throttle-body unit had to be replaced, and would have been under warranty if I had driven it more in the first 3 years (warranty period). The radiator sprung a leak after 120,000 miles, and a small plastic heater valve developed a crack at 146,000 miles, causing all coolant to drain out; then the replacement part also cracked within 3 weeks! But that has been it. One interior mistake was the standard power seats. When you are in a hurry to get into or out of the back seat, you need to press a button and hold it to move the seat forward to give enough space to climb in and out of the back. This mechanism has broken on BOTH of my front seats; the passenger seat now cannot move at all; it cannot even recline. I have not had it fixed because the estimate for parts and labor was close to $1100! Speaking of the back seat, you would be hard-pressed to find a two-door car with as roomy a back seat as this one. Back seat passengers have a tremendous amount of room. Because of the different rear-impact standards in the USA from Australia (where the GTO was made), the gasoline tank had to be relocated for the US market to behind the back seat. The result is that the trunk is quite small. I have not had a problem with it, but that's because I travel alone. My GTO has 147,000 miles now and is still on the original set of brakes! I am upset that this vehicle is nearing the end of its reliable life (how much longer can the water pump, fuel pump, hoses, etc last before I get stranded?) because there is really nothing else to replace it at a reasonable price. The Camaro design is poor (a shame because I usually love the feel and characteristics of GM cars), and I don't trust Ford (Mustang) or Chrysler (Dodge Challenger) reliability; I have heard of too many problems with them (Challenger = 8-speed automatic transmission.... ridiculous!). And I don't want to buy any technology that is older than this GTO. I don't mind continuing to pay for repairs, since I still love this car, but I just don't want to get stranded in some remote unfamiliar area, away from repair shops I trust. I wonder about parts availability in the future too, since it is a Pontiac, and there were so few GTO's built during its 3-year run (I believe it was limited to 18,000 per year?).

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’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

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

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 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.

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.

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.

Colin was great Didn’t have a vehicle that fits me, but we’re still very helpful when it came to Show me the cars that they had available
