Wicked cars, had two now, a 320 coupe and the one I have now, a 325i with M-Tech (same as Adam's). Get one with FBMWSH as they are many around, look for rust on the tailgate lip where it sits on the rear bumper, and the rear wheel arches get some rust aswell. See if you still have all the tools that are stored in the bootlid, the wheel brace which is stored by the CD Changer cradle in the boot, and the torch in the left hand side of the glovey. Other than that the engines and boxes are strong, and as already said they will clock up 200k easy. So it's only really the bodywork you need to look out for
