Faults:

Changed the alternator a few times during the life of the car.

Toward the end of it's long life, it would stall sporadically, and sometimes the computer would go nuts; The seat-belt chime would keep beeping and the interior lights would flash on and off repeatedly. This was infrequent, but could have been the result of the 4 fairly damaging collisions it had endured at different points.

Otherwise, nothing.

This car may have been built by God him/her self. In the course of 8 years, I put 250k miles on this car, giving it oil changes maybe every 25-30k miles or so after 160k. Never a tran flush. Never burned a drop of oil. Never leaked. Accelerated like a rocket. Averaged 20mpg urban, 30mpg highway, even driving it like a wild-man. The seats were comfortable for front and rear passengers.

It was wrecked 4 times, 3 times it hit deer, once it TOTALED a Honda civic. Just broke my headlight and bumper cover. That's all. Still got another 100K out of it after the last wreck

Drove it to Miami and back in the course of 24 hours straight. 2 days later, Pittsburgh and back in 15 hours. (I live in Raleigh, North Carolina) Never gave me any trouble. I was convinced that car could have competed in and possibly won the 24 hours of Le Mans. I now worship on the alter of the G.M. 3800 push-rod V-6.

When the Bonneville hit 300K I sold it for $500 and bought a Cadillac Deville. Biggest mistake of my life...

Faults:

The heater fan needed a new control module.

Previous owner wore a big whole into the driver's side leather seat.

Steering wheel controls for radio light up but don't work..

Anything that went wrong was basically wear and tear and were known problems that were cheap and easy to fix.

General Comments:

This was the best car I have ever owned. It handled like a Porsche, it had the power of a big V8, I got 38mpg on the highway which more than made up for the price of premium. It was comfortable and very easy to drive and maneuverable for a large car... I would recommend one to anyone who is willing to take car of such a special and rare car. If someone owns one they should join one of the many SSEi/Bonneville forums. They are easy and cheap to work on. The engine, with proper care and up-keep, WON'T die and will easily go well over 200k miles. ---And just so everyone knows, I saw someone say that they need 97 octane fuel, that actually makes the gas mileage and performance worse. They were designed to run on 91. It's been tested and that's what you run in it... higher test gas won't hurt it, but it doesn't have any benefits what-so-ever and lower than 91, the car won't be happy.

Faults:

Replaced rusted-out fuel lines and brake lines in the back of the vehicle, and also put in a new fuel tank and fuel pump.

Exterior sill panels under the doors are almost totally rusted away, but there is surprisingly no rust through elsewhere. The vehicle still looks good except under the doors.

The exhaust system is new, replaced within the last year.

General Comments:

I got this vehicle free when my father passed away, and I plan to drive it as reliable transportation up to 180K. The 3800 engine is supposedly bulletproof.

The vehicle runs well and needs no major items. The front seat is somewhat uncomfortable, and I plan to replace the front bench with more comfortable Buick seats from a junkyard. I'd also like to put in new speakers and upgrade the radio unit.
