I've been doing some research on the M103, because I'm thinking of purchasing either a late W126 or W124 with one of these engines. Oil consumption and head gasket issues seems like the most common problems, so I'm curious how many forum members have encountered this.

Please post if you have a W124 300E, CE, TE or W126 300SE, SEL and include the following:

Year:
Model:
Mileage:
Oil Consumption:
Oil Leaks:
Any top end work:

*edit* Also include if the car has a complete documented maintenance history, spotty, or non-existent.
