What problems should I take care of ... ahead of time??
 

Yikes! I just saw the post about the 1993 300d, the guy was driving it at 5:45 in the morning, doing 60 mph, the (?) oil chain broke, and his oil pressure went to zero. Wow! That'll toast your car pretty quick. It's probably what, a simple $30 part.

Makes me wonder, what repairs should I do, before they break??? I always change the oil, filters, and fluids when I'm supposed to.
