I had an extended warranty on a 94 Formula. I think the car knew it had health insurance and was a hypochondriac....
In 74K miles and three years, my car spent at least four months in the shop. Opti-spark, leaky lifters, fuel pumps, EEPROMS, injectors, and two tensioners.
It was just a terrible car. Oddly enough, my old 93 Z28 had only the optispark replaced in 11 years.
