The probem with these cars (or any convertible?) was if the top leaked at all, the floors rotted out. Same thing happened to the '90 Miata that I have now - never winter driven, yet the floors were swiss cheese when I got it.
Seriously, check for underbody rust/rust repairs on that one if you're going to look at it.
Yes, there are. Or you can source a Swift GT twincam 1.3L drivetrain and it bolts right in for 100 hp instead of 55. (Rats - I already parted out my Swift GT!)There must be turbos, headers, superchargers, hot cams and whatnot available for this little motor. I hope. This will be my triple cyl. hot rod!
