Pontiac Bonneville Reviews

I WAS AT THE RED LIGHT AND MY CAR JUST SHUT OFF WHY

Purchased 95 Bonne in 2006 w/106m miles, supercharged SE w/ auto climate controls, leather w/black exterior and love this car. Replaced the supercharger and manifold gaskets and have not had any issues since. Now have 164m as I avoid driving this car on bad weather days, trying to keep it from rusting prematurely in this MN salt environment. I have had several early to mid 90's Bonnes and several 2000+ Bonnes and have found the older Bonnes to be much more reliable than the 2000's.

Bought this car brand new, and just sold it at 200,000 miles - my auto tech said it would easily last another 100,000 miles. Great car with lots of features that are not on my 2004 bonneville. Some rust along the bottom of the doors - very minor. Otherwise, was in great condition.

Owned my Bonneville from 2005 to 2011. My favorite car ever. No major issues with it in all the time I owned it. Got it serviced regularly, replaced brakes, tires, serpentine belt, and had tune up at 100,000 miles. Replaced battery (after I found it - under back seat - my least favorite thing about the car). I put over 70,000 miles on it while I owned it and it has over 135,000 on it total and still running fine. For me, it was an excellent car.
