Ah, the Wankel Roadster... I find these things delightful, even if they were not much more than mere test beds for the Wankel engine. It's not even that badly-designed in my eyes, it's a very cheerful set of lines. Of course, living with a Wankel engine is the hardest part of the ownership of a Wankel Roadster, but it's better to do it now that technology is more advanced (and more capable to deal with these sort of issues) than try to live it in a time where the Wankel technology was pretty much unheard of.
I'd love to have a simple trip with this, just taking it slowly and enjoying the drive. It's a cool car.
