  Not what I thought it was gonna be... - 2005 Pontiac Bonneville
  By Aysha - November 15 - 11:46 am

  I do lots of driving I put over 50000 miles a year due to work...I put over 100000 miles on my 2002 Mitsubishi Diamante. Decided it was time for a new car, went with the Bonneville. I enjoyed the car for like the first week, then came the unreal amount of creaking in the dash, a weird thunk in the rear everytime I go over a bump, broken horn, and broken heater... this car is not what I expected...only have 15000 miles on it. The car had good power when needed and looks good but thats about it. I cant wait to get out of my Bonneville.

  Great overall - 2005 Pontiac Bonneville
  By B Udson - May 14 - 2:26 pm

  Had a few electrical problems with the seats and fog lights and curb assist mirrors. Worked out by dealer. Heads up display is very nice and a great plus. The only thing I would change is a slightly better speaker system to match the kickbutt look of the car. Great all around!!

  Awesome set on wheels - 2005 Pontiac Bonneville
  By Jfunsch - April 3 - 9:16 pm

  I have owned my GXP for two mos. now. Absolutely love it...its power, performance, ride, style and I could go on and on. Its comfortable sporty ride translate to a very responsive vehicle in all speed ranges. And I havent even hit on the power to pass or accelerate...Boy, when I stand on the throttle the V-8 jumps to life and gets you were you were going, NOW!!! My step-daughter says, "maybe we shouldnt have gotten him such a powerful car" That says it all...I have almost 2500 miles on it. It is an incredibly fun luxury sport sedan. I love the Onstar and XM satellite radio..already have paid to extend the free trials on both for at least a year.

  Best riding car that I have ever owned. Plenty of trunk space, and enough power in the V6.

  I LOVE My 2005 Pontiac Bonneville GXP! - 2005 Pontiac Bonneville
  By 2005Wht-GldBonnieGXP - August 8 - 4:36 am

  Weve only had our Bonneville GXP for 5 weeks so far - but nothing has deterred us from loving this car as Pontiac did a wonderful job! It is such a shame to see the Bonneville line discontinued after 48 great years - but at least it went out with a BANG! So far, the only shortcomings are the lack of aftermarket performance items available for it and a little lower gas mileage than I expected. But we do drive it enthusiastically as it is just a blast and the exhaust note is incredible for factory-spec. The GXP handles exceptionally well for such a large sedan and yet offers great ride quality. Luckily, I found one of the last NEW GXPs with every available option in White-Gold Tricoat.

  I priced other imports and none of them came close to this car,as far as size,performance and value.I drive approx.100 miles a day and this car is just flat out fun to drive!I have been very pleased with my purchase.The dealer treated me better than any of the import dealers I have dealt with.

  Excellent bargain. - 2005 Pontiac Bonneville
  By jocho - May 25 - 9:23 pm

  Great car. Gas mileage @ 65mph > 31+, in town, 22.5. Super ride, quiet, comfortable. Sunroof is extra-large. Exception bargain, if youre looking for a superior, comfortable, car that gets great mileage. Picked this one up used, 14,000 miles < $19.5K. List for a new one is over $35K. Thanks for earlier reviews, they helped make decision to buy.

  Love-Hate Relationship - 2005 Pontiac Bonneville
  By andacious - May 21 - 7:12 am

  To start, I love Bonnevilles. I owned a 98 Bonnie all through high school and college and it served me well. Bought this GXP once I graduated, and its definitely a love-hate relationship. As far as style, this car has it. Interior, exterior, handling, performance - all fantastic. However, the biggest issue I have with this car is the reliability. I bought it with 64k on it and in 2.5 years Im at 83k and have put over $8,000 worth or repairs into it (I have a warranty). There is no way that it should need this many repairs when its just a daily driver with less than 10k a year.

  Awesome Vehicle, Bring it back! - 2005 Pontiac Bonneville
  By jdkan1 - March 25 - 3:50 pm

  Well, about one month after we purchased the car, it had a recall on a steering linkage. Since then (it now has over 100,000 miles on it) it is going strong. Good mileage (20 in town 29 on the road). Bullet proof 3800 Series II engine. Only the normal wear and replace things such as tires and brakes. We just did the first tune up and are getting ready to replace shocks, struts, coolant flush and refill, new surpentine belt and transmission service, hope for another 100,000 out of it! One of the best cars weve ever owned for durability and comfort.
