  Love to drive, hate to fill-up - 2008 Pontiac G8
  By Rob - December 4 - 9:46 pm

  Had it for three weeks. Still cant wait to get in and drive it. Extremely impressive performance, great stereo, slick looks, but unimpressive gas mileage - 17/24 mpg. Ad says "V6 Fuel Economy"...mis-leading to say the least. My daily driver is a 00 Bonneville that gets 25/32 with the 3.8 L V6. I bought it for the overall value and "driving excitement", not the mileage. Had a tough time deciding between G8 and Charger R/T. I think I made the right decision. Beware, gas cap door blew off in the automatic car wash! Dealer wants $80 to repaint it. I say it is a design flaw.

  G8 GT THE CORVETTE OF LARGE/MID SEDANS - 2008 Pontiac G8
  By JUNIOR - September 22 - 6:53 pm

  This car is very beautiful in the exterior design. The fenders around the wheel area are amazing. The aerodynamic feel to it is great. The upshift is smooth as possible. The gas mileage is much of a concern when you know what your getting into (G8). The interior is also awesome. No Navigation or XM radio but the thing is that you are going to have to pay for XM after your first year. And you can a navigation anywhere. The Red Digital Battery thing is okay not the greatest but its not the biggest of concerns in the fun car matter.

  "Mean" look vehicle. I have never owned a vehicle which causes so many heads to turn as when I drive by. I even had a Pontiac dealer who had not yet received a G8 chase me down to look at my car. I have the Sedan, which is quicker than a lot of V8s. Some cheap features such as flimsy door handles and no XM is disappointing. Cheap stereo controls on the steering wheel. Flip open key looks cool, but seems flimsy and surely will not last. Hugh trunk and great back seat leg room.

  Saved my life - 2008 Pontiac G8
  By thankful - July 7 - 2:23 am

  Only had 5400 miles mine when a tractor trailor hit me and drove me off the road and the car rolled over. The car is a total loss, but I walked away without a scratch. not only was this a great car to drive, it saved my life. I plan to go out and get 2009 G8 as soon as the insurance claim is settled.

  GM got this one right. - 2008 Pontiac G8
  By Rod - April 15 - 5:10 am

  The G8 has every thing one would want in a car. It has awesome performance, great looks, comfort, great road feel. One of the things that impressed me the most was the reaction from the mechanics I work with. Even our resident cynic thinks the car is awesome (he finds flaws in every car but none in my G8 GT). T The G8 is a very solid feeling car, the ride is not for luxury ride lovers, it is to firm and handling very responsive.

  Car will make you excessive compulsive - 2008 Pontiac G8
  By Rod - March 23 - 4:00 am

  3 months and 3500 miles and this car has come alive. You stand on the gas and there is a sound you cannot believe till you experience. You look at the hood to see if it is collapsing as this monster 6.0 sucks air in, it makes a more awesome and powerful sound than my 70 426 Hemi Cuda did. If you love cars you will love the G8 GT, all you have to do is test drive it and you will want it. If you want a ultimate performance you can afford this is the best deal out there,.

  Well Pontiac outdid themselves with this car. Not only is it a beautiful looking car with a great comfortable interior. I have two kids and possibly a third. I know I can fit all three seats in the back seat with no probs. The best thing of all is the power this car has is unbelievable and Ive yet to push it because of the newness of the car. (no kids during testing) Its sleek,comfortable, and rides like a dream. I cant give this car a perfect 10 because I dont know how reliable itll be. As far as gas I give it a 10 because I knew what I was getting into buying a V8 and I think its getting pretty good mileage for a beast of a car. I highly recommend this car. U wont be disappointed.

  More fun for the buck - 2008 Pontiac G8
  By Rod - March 13 - 3:43 am

  In my last post I mentioned that a Magnaflow exhaust system would be delivered the next day. Well, it was and it made my G8 even more fun. The exhaust made the car sound great, with out making everyday driving to noisy like other systems I have had. Another upside is that gas mileage has gone up from a average of 16.4 to 17.1 in every day commute.

  Put another Shrimp on the Bar-b!! - 2008 Pontiac G8
  By danevick - January 31 - 4:06 pm

  When you have a bad back like me, a vehicle must have a comfortable seat. What Pontiac doesnt tell you is that BOTH front seats actually have 10 way adjustments with the premium pkg. Ive owned Lexus, BMW and Mercedes, and this car is the equal of any of them. The level of refinement is unbelievable for the price, and, I can actually sit behind myself with room to spare, which I cant even do in a Suburban, since I set the seat far from the steering wheel. Back seat comfort is also great.Throw in 361hp, great ergonomics, Bavarian looks, uplevel materials inside, and better than Mercedes build quality outside, and Pontiacs got a WINNER! Go for it before theyre gone because of CAFE regs

  I love this car! - 2008 Pontiac G8
  By JTB - January 27 - 7:00 am

  I have about 9500 miles on my 2008 G8 GT. I drove BMWs, Mercedes, Infinitys, etc. and this was the car I just simply fell in love with. Talk about fun to drive. Even after 9500 miles I still look for excuses to drive it, sometimes making 3-4 trips to the grocery store (my wife thinks Im reformed)! I have installed several bolt on high performance upgrades (cold air kit, tune for premium gas, shorty headers with high flow cats keeping the rest of the exhaust system completely stock). The car hauls now. If I get the jump on a corvette its by-by baby! The seats are more comfortable than BMW or Mercedes, no kidding. its very quiet, but most of all, its fun, fun, fun! Reliable too.
