1990 Oldsmobile 88 Reviews

Somebody ran into the front of my car and the bumper and headlights are done. How much do you think it would cost to get fixed and where can I find the parts?
Okay--I had an '87 88, but I have to review the car anyway, as it was my first. Strong engine, and absolutely a Detroit tank of a car, but it was comfortable as hell and low-maintenance. Problems: the headliner will sag on you as only GM headliners can. You will develop timing chain and valve problems over time.
