I like them too, and they're supposed to be bags of fun once they're sorted out. Hard to find a really good one though; few people are willing to put $$ into a car that won't be worth much when it's done.
I'd also struggle to spend money on a car that isn't particularly attractive. If I was going to have an oddball, high-maintenance, Maserati-engined coupe I'd probably get a Citroen SM.
