I read about this an automotive design magazine (that was also printed in Italian!?!). They compared the new FT-86 to this old British flat-four sports car (which I'd never heard of) so I thought I'd share it here. I like how the whole hood...er, I mean bonnet...lifts up so you can work on the engine. I be that makes it easy to change the spark plugs.
My guess is that changing the spark plugs on the new FT-86 will be a huge PITA. (Buy Band-Aids, remove front wheels, remove inner splash guards, apply Band-Aids, etc.)
EDIT: I think the Jupiter had a firewall mounted radiator. You don't see that anymore. Only exotica cars like the Lexus LF-A don't mount the radiator front-and-center.

The firewall mounted radiator sounds dumb until you figure out that it dumps into the low pressure transmission tunnel. Not bad. The radiator is totally protected back there, too. I don't even think the car would need a heater core because the whole radiator is RIGHT THERE. lol
