I found a 320 wagon advertised in auto week this week:213000 miles, $5000.00,owner states uses a little oil but does not smoke.Could not tell me how much.No leaks , interior near perfect.,body very clean,no rust.Could not tell me if it will pass emissions (not required in his area).Head gasket and wiring harness aside,what other issues should I look for with this mileage?Evaporator was done 6 months ago. Thanks, Dan
