  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.

  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.

  So far the car has been greatwe have 3700 miles on it and its been great so far it was nice to see that they droped the northstar motor in it AND gave it 18 inch wheels. Hope it lives up to my 98 grand prix GTP that car was great my last bonniville 01 that we exchanged for the new 05 was just a nitemare allways in the dealer for repairs
