My ex had a 210bhp JCW Cooper S convertible. I looked like a big gay bear driving it, but it was bloody hilarious!! You can get them for around £3600 now, so the list is now:
JCW Mini
Clio 172 cup
Clio 182 (cup chassis)
Early Honda S2000 (bloomin' good shout)
Mk1 Ibiza Cupra
I've driven all but the Ibiza and 172 cup, so I'm going to find one to test drive. Aren't these the ones with all the safety mods removed and nicknamed the 'widowmaker'? I've driven a normal 172 which was pretty good. Is there a huge difference between it and the cup?
