I've heard this story a couple of different times now and have always wondered about it's authenticity. Yenko would send someone to the ractrack to look for Yenko's being raced. After seeing one go down the track, this person would approach the car in the pits or staging lanes, write down the VIN# through the windshield and promptly void the warranty Monday morning. This story seems fairly feasible as it would make terrible business sense to warranty cars being raced.
