I bought this car from a long time friend in 1997 when he bought s new corvette. The ZR1 original production ran from 1990 through 1995. Only 6,000 of these high performance corvettes were produced over this 6 year time frame. Horse power for this car is 425 SAE net compared to 250 for the "standard" corvette for that year. The engine design was over built and the first 4 over head cam, 4 valve per cylinder built by GM. The engine option cost over $30,000 and this was on top of the base cost of the car, making the total cost over $60,000! All 16 fuel injectors were replaced on 2015. The Bose stereo head set was rebuilt in 2015 also. Car has the original laminated wind shield.
