I don't recall anything major going wrong with the car. Nothing other than replacing standard wear items on it. Tires, brakes, tune up.
One annoying problem it had, it would get fuel smell inside. I never did resolve it and basically ignored it.
It is a very mediocre, but reliable car. Nothing remarkable. Little power. High mileage, between 28-30 mpg.
The build quality was high, I thought. The interior was nicely built. Nothing shaking or rattling. It was quite inside, the seals were good.
Being FWD, it was stable on ice and snow.
I got rid of it because it had little space inside and I wanted a V8 station wagon.
I know that 93 (or 94) was the last year for Ford Tempo. By that time, it was quite reliable. On the other hand, late 80's Fords were terrible. I knew someone who always had problems with a '87 Tempo. Transmission, and much more. My experience was just the opposite. Good reliability.
My 93 ford tempo has over a quarter million kilometers on it. I am now receiving more power and gas mileage from the motor then I ever did in its middle years.
Any car that is reliable is certainly not unremarkable.
