I'm thinking of purchasing a ZR1. What should I be looking for as far as weaknesses of this vehicle. I currently own a 1986 Coupe and really have not had any problems other than regular maintenance items. I have owned that car for 11 years and driven it about 25,000 miles. Is it possible that I could expect the same trouble free years of enjoyment from a ZR1? I have been looking at many on Ebay and the prices seem very reasonable right now.
