w126 comparison question: m103 v om603
I'm wondering how the m103 compares to the om603 (besides the obvious gas/diesel)...I have a '86 300sdl going very strong at 280k miles but I would like to eventually replace it with a '90 300se. Several reasons for this switch: 1) The 300se is a more 'city friendly' car. 2) I've thought about an early 300sd, but going from a 603 to a 617 will be painful. 3) Finding a good 350sd would be a costly enterprise; not to mention concerns with the larger bore 603s.
I feel like the m103 powered 300se should provide a close enough driving experience - maybe even better being a gasser in a smaller/lighter car. This is an acceptable trade-off for me in light of the higher gas consumption.
What kind of reliability can I expect from well maintained m103? Besides cosmetic differences, are there any major differences in the m103 w126 cars from the 1988 through 1991 model run?
My goal would be to find the lowest mileage and best maintained example in the $4-5k price range. Thanks!
