I have completely rebuild the motor, mostly because I wanted more performance. The only things that have gone wrong before rebuilding were the Alternator went out at about 75,000, the transmission at about 85,000, wiper motor at 110,000, and currently the car is going to be repainted and a rust spot fixed along with a window motor that is about to die. A solid car, and I am not very nice to them I drive very aggressively 1,000's of miles at or above 100mph.
Great car at high speeds, over 90 it rides, handles, and overall performs incredibly. I have the 5 speed car and at speed it is not a problem to get almost 30mpg. Not the fastest and not the slowest, it will give the new cars a run for their money as well as some of the old, fun to drive for a big car.
So you drive a 15 year old car with 135K miles on it over 100 mph?
Are you suicidal, or just stupid?
It's a cougar it can handle it. I drive my 79 Pinto Wagon in the same maner. 142XXX and still going!!!
