Frank,
surely that 'only' similarity is true of pretty much all 'kit cars', or spaceframe replicas...
Many don't have the same brakes, steering, or even the same ZF transaxle, and a lot have different engines too. Sure, its not correct for the purist, but the CAV looks every bit as good as any of the other spaceframe cars on the market. The engine choice isn't to my taste either, but it wouldn't stop me considering the car if I were looking.
Maybe I've missed the point. Is the chassis flawed in some way, does it handle/go/stop like a bag of sh!t, or something else thats not obvious from the pictures ?
I think the floor looks superb, and the car would have almost certainly helped to draw people in. I'd be happy to have either in my garage
