So keep the car running as long as I can reasonably when the motor goes replace with the better version but dont sink allot of money into it. So im buying struts , mounts and shocks and thats about it leave it alone. Seat covers if I see a set I like . I am a mechanic so all the works done by me but I know my limits 85 was not a great year for cars in general they hadn't figured out the economy thing yet so there hard to diagnose .The m111 motor will it match motor mounts so I can just drop it and bolt it to transmission and go or do I need a diffrent cpu guessing I do.

Note I use a commercial account to buy parts all three motor mounts a 100 dollars front struts 60 dollars a piece 12 dollars for mounts shocks are 20 dollars theses are original mercedes parts from world pac if you want to check .
