This info. may have been posted and I missed it, and I, too kinda remember the article, but...is the ZL1 a later version, or a numbered unit from a car, or a vintage over the counter engine?
Love the car!!!

This car is killing me, please someone buy it so I can quit dreaming about it.
This has to be my favorite color combination, and the RS equipment is nice. |
