The mechanicals are all TR4A-TR6, so pretty easy to replace with new or used, check the engine for the dreaded crank float from worn out thrust washers, good advice on the rust already given, the badges are unique TR250, so expensive if missing or bad to do them all, the wheels, if not wires do they have the correct hubcaps in decent shape, if not you need to spend some money on either wire wheels, used TR250 hubcaps, or some sort of alloy or aftermarket wheel (unless your goal is a rat rod of some sort with steel wheels) None of these options are cheap. Interiors are expensive to do if you need seat covers, crash pads, interior panels and carpet, in fact in terms of raw dollars I spent the most on the interior by far (a considerable amount of sweat equity was invested in the rust repair, bodywork and mechanicals).
