Drove one a LONG time ago.
RHD, Sprite engine, skinny wheels, much quicker than my Bug-Eye and made square corners without drama.
About as much fun as you can have with your clothes on and no divorce worries.
I've always been grateful to the owner, he trusted me with his toy when I was a complete stranger to him!
A couple of years ago I found out that he STILL owned the S2, which he bought new.
If he's still around he has to be in his eighties now.
So beware that an S2 might just hang around for a long time.
