unlimited budget, what would you do?

I'd like a Caterham CSR 260 thanks,
"This Cosworth-powered roller skate will hit 100km/h from rest in 3.1sec, tops out at 250km/h and, the makers say, delivers more smiles per mile than anything else on the road. "

While it would be easy to just splurge it all on a supercar and leave it be, I think we're all too much of the tinkering/fiddling folk to leave it at that.

I'd love to experiment with mid-mounting engines in all sorts of ordinary cars. A Mk3 VR6, a Mk4 R32, a wrx, the list could go on forever.
