add to list:
central locking faults, rear archs (behind door) tailgate dropped (and thus a ****** to open/close, loud diffs/gearboxes, rust above windscreen, rear cross member, front arches/inner arches, heater blowers not blowing, rust at the top of pillars just below the gutters, any signs of identity change (check vin numbers/engine numbers match up to V5, if a tow bar is fitted check for stress marks around the chassis mounts, power steerring pump leeks, excessive smoke (particularly if blue - burning oil, run away!) electrics prone to "alterations" - make sure eerything does what it should....
usual stuff to look for as with any vehicle, obvious accident damage (dont expect to find one that hasnt had the odd knock or scrape) head gaskets, oill leeks, brakes, fluids as they should be etc....
other than that they are great!
