I know a couple of peaple with them and they have no complaint's.
The most common problem ive seen with them is the rear 1/4 panel
at the bottom front corner's of the rear window's tend to crack! which
is within the seat belt mounting point's. The only other area ive seen them rust
is the driver's side front chassis also common but not a major problem
to deal with. Apart from that i dont think a lot else apart from wear or tear
goes wrong with them.
(the bit about the rear 1/4 panel's only affect's the 3dr corsa's)
