  nice car-poor quality - 2005 Pontiac Bonneville
  By chaps - October 25 - 3:40 pm

  Love that motor, handles nice with a good ride, overall a rewarding car to drive. Quality is poor, car is midnight blue and the primer shows through all over. GM wont respond so Im going to BBB for buy back. 13 new GMs in last 20 years and this is how they treat return customers? Very unhappy with the fact they wont meet with me. Time to look at the Imports.

  Never Again - 2005 Pontiac Bonneville
  By Mikki - August 24 - 7:26 am

  Not a good car through rain and puddles. It only has 27,000 on the odometer and the trans is shifting hard, clanking noise every now and again in front. Brakes have been fixed once and checked three times. They still squeal. Mechanic says its the brakes they put on cars these days. Also has blind spots. Paid $22,000 and is simply not worth the money. Im trading it in A.S.A.P

  Could have been better - 2005 Pontiac Bonneville
  By cmsherm - March 16 - 2:33 pm

  Style of the body makes the vehicle look welcoming due to the fact that this looks more like a sports car than the traditional family car. The interior looks much more inviting than most of GMs bench seat in the front of their sedans. However, looks can be deceiving. The seats are very uncomfotable and traveling long distances make riding a horse seem more appealing. The vehicle has good acceleration once you get out of first gear and the exhaust has a nice rumble when you hit the gas. It is fun to drive on winding roads due to the wider wheel base. You can find curves that suggest 30 mph, all the while you can be doing 60 mph mashing on the gas and never leave your lane.
