  Great Ride - 2005 Pontiac Bonneville
  By Mike - January 26 - 8:30 am

  Only owned for about a month but so far very impressed. Expert reviewers missed on this one, traded 300C which was a terrible car, nothing worked after 3 months, GXP has great drive train, more than enough power, very good handling for a front driver. MPG so far is about 17/22 which should only improve with time

  Bonneville Good But Bad - 2005 Pontiac Bonneville
  By fig newton - November 7 - 2:33 am

  GPX is a great car, but if you buy a used one please get a 0 deductible warranty. Have had $6000.00 of work done. lucky all but about $800 was covered (Shocks and brake-not covered), all problems caught by dealer during normal maintenance. The problems,oil and H2O leaks, rear drive problem, Onstar/radio, control for heat and air condition, wheel bearings eta. I have one year left on warranty- lucky me.

  By Sam Abraham - October 29 - 12:20 am

  Air conditioning leaves a lot to be desired. In 95 degree weather it did not cool even when recirculatimg the inside air.

  Great car - 2005 Pontiac Bonneville
  By sharon - October 4 - 2:20 pm

  For the price this car beats everything sports luxury car on the road. Great power. Has features that of luxury cars $10k more in price. Handles great. Large trunk and very comfortable seating. Like it so much I decided to purchase it at the end of lease. Cant find anything comparable in its price range. Excellent safety rating. Bring back the GXP!

  Studied them ALL for six months and decided on the GXP. Looks, Power, Handling, Comfort, Value and its American! Purchased used for 12,000+ under MSRP. Today you good do even better!! Highly recommend for us sports car lovers that need a 4-door business car to satisfy the Boss! Mileage 17/22 and I do not expect it to get better with already 22K miles on her!

  Bring back the Pontiac Bonneville! - 2005 Pontiac Bonneville
  By S. Dodson - April 12 - 9:43 am

  Many heads turn when I drive by. The attention could be because of the sexy, throaty sound from the exhaust, or the look-alike lines of a NASCAR racing body. Ive been asked what kind of car it and in the same breath ask, "is it a Pontiac". Then they say, "nice looking car". The lighted dashboard at night looks like the cockpit of a 747 - love it! I can only wish that the Bonneville will return in great splendor; otherwise, I must go the way of Dodge -- Charger that is.

  By Robert Dumont - February 9 - 7:06 pm

  On a recent 1200 mile trip this car performed flawlessly ,very comfortable as any autos out there. Gas mileage was 31.6 mpg when run at speeds of 75 to 80 all day.Ive had more complements on this car than i ever expected.I would strongly recomend this car to anyone who wants a near luxury car at a reasonable price.

  2005 Pontiac GXP - 2005 Pontiac Bonneville
  By Mike Wandell - April 13 - 4:56 am

  I really love this car, I am in sales and drive it all over. It has all comfort I need and the the power when needed. I almost traded it in about 6 months ago on a Cadillac CTS. I took the Cadillac back and got my Pontiac back. The Cadillac was not as good as the Pontiac. Its just a lot of fun to drive, at night the dash looks an airplane cockpit.
