Awesome, proper custom cars then! I used to own a Mustang (first generation after the fox body) and my neighbour across the road has a Trans Am, a Camaro, and something else that's in bits in his garage. There was a small show at Gwrch Castle last weekend run by Corvettes by the Coast, lot of very nice machinery there an not just 'Vettes either.
That looks like an awesome T-bucket, what's under the hood??
Unfortunately I'm not going to be attending any games this month myself, I've got a bike rally in a couple of weeks so I'm trying to save my cash for that. But I agree with your idea of a big engined trike, I've seen 'Busas and a ZZR1400 but not a Blackbird one, although it's not as if the engine wouldn't have the power for it!
