Consider this: the 1989 Corvette had 245 Horsepower V8 and would have weighed 600 lbs more than the 200 horsepower DOHC V6 1989 Fiero.

The Fiero would have more than likely at least matched the Corvette’s performance at less than half the price.

Even though sales for the 1988 model year were set at 26,401, the sales would eventually rebound, due to a $30 million dollar investment for the new suspension which corrected all problems the 1984-1987 models had and offered the new design for the 1988 and 1989/1990 model.
