At a smart Roadster weekend camping meet we arranged a few years back had one guy driving his Roadster around with his girl friend (also a Roadster owner) sitting on his panel that sits between the B-Pillars for some photos to be taken (all tasteful I'll add) - she left a lovely bum print in that panel, it is much thinner than Morgan wings (the roll bar frame sits under it) he wasn't to happy! The rest of us could hardly suppress our giggles!
