So, how about this? :
850 Mini - Slow, very cheap (And I would guess VERY insurnce friendly!)
Sort it out, fix up the body and such, all the normal mini problems (Rust etc)
Then, Pimp up the inside with white leather, cream carpet you get the idea.
May sound tacky, but a set of Hydrilics. Not the basic, Higer, lower air powered ones... Im talking the kind you see on the US Loweriders! The bouncing ones!

I know where I can get the hydrilics and other mini bits, but does anyone know of a place where they can make Custom alloy wheels in any size? I know Im not going to get started on this right this secound! Its really going down on paper for now untill I can get a better paying job and finsih at Universty.
I reeeaallly want to get featured and a "one of a kind" mini! So, why not do it with some stlye? UK Lowrider Mini project is a go!
