Used 2006 Pontiac GTO for sale near Milwaukee, WI

Very easy process and listened to what I wanted vs what they wanted to sell me. Good service! They also have followed up after my purchase to see if had any issues. I feel like I can always get the help I need.

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 purchased a 2024 Mercedes G Wagon 63 AMG from Steel Chariot in January 2025, and the entire experience was fantastic. Nima, the owner, personally helped me with the purchase and went above and beyond to make sure all my questions were answered. He was knowledgeable, professional, and genuinely cared about making the process smooth and transparent. The dealership had a great selection of high-end cars—plenty of impressive options to choose from. The customer service was top-tier, and I never felt rushed or pressured. If you're looking for a luxury vehicle and want to deal with honest, helpful people, I highly recommend Steel Chariot. Thanks again, Nima and the team, for helping me find my dream car!

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!

Kyle and James made it happen for me. I walked in there and they said we can get you financed 100%. I had no doubts. I have done business with them in the past and I was confident when I walked in there. I recommend everyone to go get a car from them immediately. Awesome customer service. Moses is a magician. They made it happen..Thanks guys

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 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.

Impressive mix of inventory at great prices and their highly professional staff is friendly and will not pressure you!

I Loved imports all my life and still own a new and old R32 and R35 Skyline. Nothing like a import Turbo Spool and Blow off Valve. However I own a 2006 GTO as my daily driver. In fact this is my second 6.0 GOAT. They are Cyclone Grey. 1st one I had I sold to my brother who loves it. So far I've done every Full bolt on you can think of. From twin xxx rear mounted turbos, Long tube headers, highflow cats with X pipe. Front mount intercooler,ported throttle body from a c7 vetted. Basically everything that goes along with a twin turbo setup. At low boost (26lbs) On a mustang dyno, it makes around 920 hp to the ground. 1100 ft lbs of tq. Now im sorry for the list of parts. However I've had this set up for 3 years now and running high 9's in a 1/4 mile. I drive to the track and drive home. 690miles to and from. This car is insane. The only issue I ran into was having to roll the fenders for bigger rear tires. Which are now 305s. (275s) for daily which actually fit on the stock oem wheel. Oh also the stereo is trash. Lmfao. So I upgraded to a set of 10 speaker bose with a 1500 watt amp right next to my fuel cell in the trunk. Other than being a vette and viper and lambo killer. I would strip all its parts and ride this car stock until the wheels came off. Point Blank Period......

Everything was great. They were friendly and was willing to negotiate a price I was comfortable with. I most definitely will go back to purchase another car if I need to.

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.

Great experience easy communication employees were all friendly will stop by in the future for the next vehicle

Autos of Chicago truly impressed me with their exceptional customer service and professionalism. From the moment I walked in, the staff greeted me warmly and took their time understanding exactly what I needed. They showed me several used cars, explained their features clearly, and were completely honest about pricing. The car I chose was clean, well-maintained, and fairly priced. The entire process—from test-driving to paperwork—was smooth and stress-free. I’m extremely satisfied with my purchase and highly recommend this dealership to anyone looking for a reliable used car.

Amazing customer service from this dealer. Highly recommend. The dealer showed a high expertise and helped a lot with all the paper work and bureaucracy

Jad, The salesperson was absolutely fabulous! He really knew his stuff and shared everything with me without any pressure to purchase the vehicle. Probably the best salesman I've ever dealt with and I'm 72! Steve j. Sisson

Hector did a great job as always, keeping us informed on status. The turn around time was good and we were treated with courtesy by staff.

Mr Zeidan has been great to work with. He has answered all the questions and concerns and very helpful. I will soon be purchasing the car of interest.

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.
