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.

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

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.

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 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 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!

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.

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 😊

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 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.

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 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 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.

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

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!!!

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.

I have been searching for a Saturn sky for about a year. I was fortunate that I found this dealership on the internet and was able to find exactly what I had been looking for. I was really apprehensive about buying a car sight unseen and from a stranger with the fraud schemes that happen all the time but I talked myself into it. The customer service was fantastic, the car is immaculate and everything they said it would be!! Thanks guys for restoring my faith in humanity. You are truly one of the good ones and I will recommend you to everyone.

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.

I had my Porsche in storage for the winter. I was involved in an accident with my daily driver and totaled it, so I needed to get the Porsche out of storage asap. Usually a 30 day notice is needed, but the staff made it happen to get it done asap. That is Customer service!! I love that place and their staff and I maybe one I could be working for them 😎

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.

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.
