I think I will go with 190 any engine type, If gasoline depends on MPG if 20 less I will converte to Diesel. I hope i'll catch a manual trany car, so i could just drop old and put new rebuild in.
Well now I set my gols. I'll get my Juniar licence soon and go shop for a car. :-)
Wish good luck.
I'll be around here some where.

 

benzbob,

Is it hard to find parts for the 87 since they only made it one year?

 

Then i'll just fabricate some. :-)
And I found easy solution for winter, put about 4 gallons of gassoline for full tank of diesel. She will start from half turn.

 

Oh!!!! Well I don't know about gasoline and diesel mix, I have heard that if you accidentally put gas into a diesel car, a gallon or so to a full tank of diesel wont kill it! But 4 gallons I might want to drain the tank!

Parts for the 87 300D are no problem. There seems to be no shortage that I'm aware of. Remember, many of the parts for these OM6XX engines, from 86 to 95, and I think also 96-99 share many parts. For example, heads are available and plentiful as most all the six cylinder 6XX engines have the same designed head. The head on my 87 is a #14, and there is a rare #15, but the #17 thru #22 were refined and would no longer suffer overheat situations. Precombustion chambers in the #22 are not compatible with older heads only.

Body parts, climate systems, brakes, are pretty much the same for all 124 model cars with only slight variations. These 124 cars came in nearly every conceivable body style including wagons, convertibles, sedans, coups, and the $160,000 "Hammer" from AMG!

There is likely to be parts available for a good many years to come.

 

Usual mix is 80% diesel, and 20% gassolin. It brings down the octane number and it becomes easily igniteble. Cheap way for winter.
