very nice.
Welcome to the forum!
my 78 is in MUCH worse shape... PA car. passed PA rust inspection... with a bit of welding... blew a head gasket when PO changed the DREADED SERVO... I suppose he did not burp properly, and left air in the head... he wondered why the temp gauge never read warm after the repair
if the seller has not put a fuse in the water circ aux pump, get one in. also keep that cooling system in top shape. the servo's are quite pricey, and problematic.
mostly though ENJOY your MB!
