Seems like a pretty good deal. Be sure to check the rtab pockets, radiator neck and hoses, expansion tank for cracks, rear strut mounts and suspension when you drive it. Most shocks are done by 75k. Wheel bearings may need replaced, control arms and control arm bushings and be sure to ask about service history. Id honestly ask the seller if you can get a 3rd party inspection.
Just my 2 cents. Built an e36 m3 track car from scratch the past year...
