There is something else very unique about the RS-ZL1 that wan't mentioned in these posts. The engine that currently sits in the car is not the factory motor. The factory motor had to be replaced within 6 months of the car's original purchase. Somehow the motor was later found and rebuilt. It was sold along with the car and was mounted in a steel frame on wheels they were pushing behind the car when it went up for auction. They even cranked it. They said the ZL1 motors alone are worth 50k today.
What an awesome car.
