u guys need to realize you arent getting a new car... these cars have a little age, and time wears them out.... if u dont want any problems, buy yourself a new car and be done with it....when u buy a new car, u have a payment every month... wwith a used car, u pay it off, have no payments but something might break or go wrong, thats the risk u take when getting a used vehicle, any vehicle, not just mercedes....

Common weak points. Most are included in rsmcmahon's list, but

I thought I'd highlight the common failures that I've learned about since watching this board.

Air conditioning evaporator
window regulators
closing assist pump (if your 300 has it)
central locking pump
engine wiring harness (any wiring harness for that matter) up to MY1995
duo-valve (valve that routes hot coolant to the heater core when the heat is turned on. Failure means no hot air from the heater.)
Blower regulator failure causing erratic (usually slow) climate control fan operation.
Probably a couple others that I'm forgetting this moment
