Wow. Lots of young Corvette owners here. That's good to see.
I'm not as young (damn!
) and I have a '91 L98. The 1991 has the late C4 body and interior but with the 250 bhp L98 motor. I agree with vettelt193, the L98 is torquier than the LT1 and delivers that torque much lower in the RPM range. The result is that the car is a bit more fun around town. Is it better? I don't think so but it's not inferior to the LT1 either. When I'm driving it I never feel like I want an LT1 nor even think about the 50 bhp difference, because the performance of the L98 is more than enough for me. 0-60 in 6 sec or less isn't a stone! Although, I know that to you whipper-snappers, half a second means the world!
"Whipper-snapper". There's a word you new generation people need to pick up again. LOL! I'm 37 and MY generation hasn't even picked that one up either!
Like everyone said, buy the newest, lowest mileage, and best condition C4 you can afford. However, don't turn down a 1991 with the L98 because you get the looks and solidity of the newer C4's with a proven, reliable, and relatively simple motor (no optispark). Plus, it will not cost as much as a newer C4 with the 300 bhp LT1.
