Cooling system Johnny (Water pump/thermostat/rad etc). Once this is done they're very good. Think mine had 165k miles on it when I sold it and apart from standard service items and a clutch, it was very reliable.

If you can stretch your budget a bit, I'd try get a nice facelift m-sport model like my old 05, with the 18 inch MV2's. I still think they're a cracking looking car. I'd also try get one with leather and an armrest. Mightn't be as big a deal to you as you're a short ar*e, but I found it very uncomfortable without the arm rest!
