If you do go looking for one I'm sure you know the general things to look for. As these cars are knocking on a bit now, check everywhere for rust battery tray, by the fuse box, front slam panel, rear arches, rear beams. Always make sure it's cold when before it's started, check oil making sure it's not milky, check for any sign of leaks etc. When it's started have someone stand at the back make sure it's not smoking & when it's running check again for leaks especially around the turbo as these can be expensive to replace. As tempting as it is don't by the 1st one you look at check around a few others as well just to see what else is out there. It is near on impossible to find a mint one but there are a few out there but they will be priced to match the condition.

Again HTH
