From time to time, you see very nice C4 ZR1 Corvettes come up for sale at very reasonable prices. I understand they have different drivetrains front to back than what you get in a regular C4. Understandable given the big hp increase over the L98 engines. They were pretty well bullet proof right from the factory but everything eventually needs attention. Not being able to get parts or having someone who knows how to repair them could put a real damper on a rather fantastic car. Manny??
