I'm looking for a C4 (93-96) Admirable Blue convertible corvette in Ohio and I want to know the differences in the two motors, is it worth the extra money, and insurance cost. Looking for mid-low miled car with black interior. Planning to put after market exhaust, K&N, etc. what's the horsepower rating etc. what are some other good items to have on the C4, like FX3 etc?
