My throttle cable got stuck once after a rather "quick" take-off. Other than that, nothing.
I love my Olds! I got it for $1,000.00 at a used car lot, put a compact disc player in the dash and plan to have it painted soon back to the original color. It is a fantastic car and a pleasure to drive as well as ride in.
I also own a 1977 Cutlass Supreme. I think they are great cars also. I've never seen a car that can take such a good beating and still run like a CHAMP.
