Purchased new 09 of 2008, after 64 months of ownership, this vehicle has been nearly perfect. We only drive it 2 or 3 times a month. Averaging 20.8 mpg over the last 3800 miles of mixed driving. Current mileage is 23,600 mi. of old folks driving (treat it like we paid for it).Over our adult life we have owned 30+ new vehicles, & 10+ used. From Acura to VW, including a few hp & luxury types.maybe it was just good luck but the gt does everything very well.I have read the first drives of the new chevy ss, & it sounds like an excellent car, but the msrp is nearly 47k with the fuel usage tax penalty.I will keep the gt thank you. Up dated 11/25/17: Still liking the first Pontiac experience my mileage is now 34,600.Averaging 21.3 over the last 15,000 miles probably 60% hwy. Would like to have the brake pedal a little firmer. Other than that it has been every thing I would ask for.
2009 G8 GT owned 2 months 19K miles 6' tall 250 lbs male (me) This a great sports car. I bought it after buying and then having to sell an Audi S4 (I can't use a manual due to a bad knee). The G8 is very fast and has a great automatic transmission. The seats are great and the interior is large enough for adult people who are larger than a size medium, unlike most sporty cars. Factory autostart has a range of about 25 feet line of sight. This car would be perfect if it had 2 inches more ground clearance, AWD, and better visiblity.
Best dollar per pound USED high proformence vehicle

Pound for pound this is the best car for you the price. The V8 is powerful and responsive, tires get great grip, good handling the weight ratio is almost 50/50 which helps the suspension and handling but if you have the option the fe3 suspension on the GXP is better. The fact that you can buy one for under 20K and the car is competitive to hang with last model Camaro's and Mustang's that are twice the price tag is the best reason to buy this car.
I just bought my G8 GT 4 months ago, though I've been looking for one for over a year and a half. I originally wanted one when they were new but they were a little too expensive so I went with a used Grand Prix GXP (big mistake). So far I love this car. I get "nice car" comments weekly, even by my local GM/ex-Pontiac dealer who apparently doesn't get to service too many of these. If you are looking for performance and value you really can't beat this. For a new car with this performance you'd easily spend $35k.
I purchased this car 14 months ago and love it. The car comes alive on the highway. The engine and tranny are matched for American highway cruising. Bmw performance at USA prices. The build quality is very good. I get around 19mph overall gas mileage. It uses regular gas. Get one of the plug tuners for tuning the transmission. Stock it shifts to late and makes the car seem sluggish, unless in sport mode. Tuning corrects this issue and transforms the car! Tires are pricey.

Unfortunately, the most effective launch is the ugliest and most abusive, with lots of axle hop from a lowish 2,500 rpm. Higher rpm with smoother tire spin felt better, but was slower. The clutch took some getting used to, with low effort and a high engagement point. Also it feels as if there is a damper in it, slowing and smoothing aggressive shifts. The shifter is slick and accurate, however. Also, why no painted redline on the tach -- especially as this slow-reacting tachometer often is 500 rpm behind?
Very solid, fade-free braking performance. Moderate pedal effort, but so-so feedback. Still, this is a very good overall setup.
Skid pad: There's a noticeable "tipping point" where the GXP can go from benign understeer into a very slight oversteer attitude. Good balance here and a slideways drift is a piece of cake. Slalom: Unfortunately, that slight oversteer tendency we liked on the skid pad is more pronounced in the slalom, and it builds up as the cones pass. Entering with any kind of quick pace resulted in a pendulumlike, increasingly tail-happy run. The best run was earned by entering slowly and finishing strong, feeding throttle to keep the rear planted.
