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.

Got one at about 185,000 miles on it,had to replace rack,still have to put a lil pwrstg fluid in every now then,Now I can go backwards and not forward,just happened yesterday,So I guess that's my transmission

The first car I ever owned, powerful, comfortable, but without a lot of features in contemporary cars. No aux cord, no backup camera, definitely no Bluetooth. The 3.6L Supercharged V6 in the GT was a dream to drive, the whine of the supercharger spooling ingrained in my memory. I had a few reliability issues, having the serpentine belt fall off while driving and having to replace the water pump as well as having a hole pop up in my muffler which I never got fixed due to totaling the car.
