My 07' Grand Prix GT still going strong in 2023 with 10100 miles on it (low for its age). The GT had the supercharged version of the 3.8., has every option other than OnStar, stealth gray exterior, 10 spoke wheels, all charcoal leather interior. Other than regular maintenance and the normal wear items it has only had a check engine light come on once in 16 years, codes revealed a TB circuit failure, and a 150.00 throttle pedal fixed the issue. Minor issues are soft trim parts are failing and no replacements are available to be had. GM should have killed the Buick instead of Pontiac, after all it brought more to the table than Buick did. To this day still gets the 18mpg the EPA suggested in 2007.

Unexpectedly Surprised! Jim, aka Turk, the 2nd generation owner of Diamond Jim’s is a 10 out of 10 and if the scale was out of 100, he would be a 100 out 100. Here’s my story: I have had over 35 Corvettes and had been looking for a 2015 Corvette - Daytona Sunrise Orange Metallic - convertible - 7 speed manual for 18 months and finally found one and it was at Diamond Jim’s in Milwaukee, WI. I called and spoke with Jim and he suggested that we FaceTime and we did for it a good 20 minutes. Car was great except the tires were a little worn … not a problem … I put a deposit down and scheduled a flight from Southwest Florida to Milwaukee with the plans of driving it back 1,430 miles! 🤪 I have never flown cross country to buy a car before so I was a little nervous to say the least. We arrived at Diamond Jim’s and met Jim … the car was everything he said it was and better (fair price too)! This is when things turned to the unbelievable and quiet frankly, shocking … Jim said he felt uneasy selling me the Corvette with the slightly worn tires so he replaced them with brand new OEM exact factory replacement Michelin tires!! I have another, identical Corvette and recently replaced the tires on that one for a whopping $2,000!! 🫣 Jim apologized for not giving me a full tank of gas (it was 1/2 full) … I said, “Let me see, a full tank of gas or $2,000 worth new tires!!” He laughed and said the construction in front of his dealership prevented him from filling up the tank! He’s a true gentleman. Then, to add to this amazing person that I just met, Jim called us about 2 hours later during our drive home making sure that we were doing OK!! Lastly, we plan on buying another car within the next year and there is no doubt that we will call Jim, take his word for the description of the car, pay for it and ship it to Florida … we drove the 1,430 miles in 28 hours and we don’t plan on doing it again! 😁 I have been buying cars since the late 1970’s and I have never had a better experience than I did with Jim at Diamond Jim’s and I give them the highest recommendation possible!! 👍

This review is for the GXP trim. I love driving this car, its powerful, handles well, and looks really sharp. The car itself is very large, larger than most SUV's and minivans, however the interior is a bit cramped for how large it is. Overall it is mostly comfortable and fun to drive.

(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.

Everyone at the dealership was helpful. They all work very well as a team. Bruce was exceptional in his area of sales and knowledge of the vehicle.

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
