Mercedes 230 SL
Neither macho brute nor girly roadster... so it's Clarkson's choice. He says:
'Being heterosexual, I'm not sure I find any overtly masculine car sexy. And that's a problem, because most overtly feminine cars tend to be diminutive convertibles like the Nissan Micra C+C. And I don't really find that sexy either.
'The pagoda-roofed Mercedes SL, though... that's more like it. Because it has bare minimum styling, just like you get on the Kristin Scott Thomas.'
