Hello, found a 1992TE wagon that may have been sitting for 3 yrs. Car is covered in leaves and tree sap.Owner passed away and estate is taking offers on car .Car is black/black leather with 3rd seat. Odomoter shows 82,500 miles. Only seen one small dent on drivers fender and the rest of exterior looks very good. Interior looks very good except it smells like mouse pee but could see no visible damage. Car currently does not run and person selling it does not know if it does or any other history of car.It has a clear title. I know more about diesels but nothing about these gas engines. What Im' asking is what should I offer for this car and is there anything to look out for pertaining to the gas engines.I would guess it would have the same quirks as a diesel but I have no experience with a mercedes gas engine. Thank you for your input.
