I'm going to check out an 8v Mk II GTi -- what are the trouble spots I should pay extra attention to?

I already know the brake/clutch pedal assembly needs replacing, but I haven't driven it, so I'm not sure how bad it is.

This is going to be an autox/RR-only car, so i'm mainly just concerned w/ the mechanical things -- the interior will eventually be removed.

Any info you give would be helpful--thanks!
