Run your fingers around the wheelwells. If there is a seam present its been in an accident. There was a seam on the passenger side rear wheelwell and you could see a slight bend in one of the trailing arms. When a vette gets in an accident, the complete fiberglass body flexes. Not like a metal body where the damage is local.
Hairline fractures appear everywhere.
In my vette, the roofline just above the rear window had hairline fractures. I went off the road twice with it because of my own stupidity. The first time was when I was showing a friend how well it handled. He was more impressed that I could drive out of the muddy field and back on to the road. I figure this was were I broke the rear leaf spring mount.
