Power door locks don't work anymore.
Clear coat peeling off.
Power windows slow.
Headliner fell apart.
New ball joints and tie rods at about 300,000 kms.
Transmission started to slip at about 350,000 kms. Lucas Transmission Fix fixed that problem.
Cam positioning sensor at 350,000 kms.
And it has gone through 2 alternators so far.
Muffler fell off at about 200,000 kms (don't know how that happened).
This car still has it's original engine and transmission, and it's still going strong. It's very reliable too.
It's still great on gas.
Everything still works, except for the power door locks not working, and the power windows being a little slow.
Has always started no matter what temperature it is.
I will never get rid of the car, as it's one of the best cars ever built and I will never trade it for another.
Bonnevilles (1987-1991) are solidly built cars. I have a 1990 SE and it has only 199,800 kms. The windows are slow, especially in the winter. The drivers door used to unlock on it's own and the trunk as well. I solved that by taking off
the remote entry switch. My Bonneville doesn't get great mileage. It uses about 15 litres of gas every 100 kilometers.
