Hey Guys,

I'm not a big time poster here on MercedesShop but I always look around and enjoy the many threads. OmegaBenz pointed me this way a while back for great techincal information and its been great so far.

I currently am in search of a used M103 motor for a 1991 300SEL that has under say 100k miles. The motor is for a close friend whos car is in impeccable condition but the 320k mile old engine is just beyond repair at this point. He cant even think about parting with the car due to all the effort he has put into the car thus far but sadly the motor has seen better days.

Instead of re-doing piston rings and re-building the head I figure it would be cheaper and easier to source a sold engine with a long life left in its future.

If anyone has any leads I would love the help.

Thanks in advance.
