Nothing apart from needing new brake pads and new tyres where my 18 year old son keeps on doing wheelspins in it.
An excellent car for £275, no rust, passed MOT first time and came with tax. Only niggle is that the steering wheel hasn't got rake adjust, only height.
I have one to, but mine is great I have a carburetor problem, but its so old that's cool apart from that its got great reliabilty a great car.
