Cheap w114/w115 just keep showing up

This one isn't too far from me and the guy wants $1300 and really just needs cash bad.

Mercades 300d w115 1976

This one looks nice, having power windows and being a 300d, the biggest motor made. I know these cars are slow, but this one could be a good grease car, right?

I hate the big bumpers, but if this thing if a better road car I could certainly take the bumpers from my white sedan or maybe even one of my coupes. Heck, there are enough bumpers for sale for these cars anyway.

Too bad the paint sucks.

In the present condition it is maybe a $500 car. Rotted out floor will need more than the hack fix it has. There is far more rust than he is admitting to. I had a W115, and the rust is in all the places he is not mentioning. The floor rotted out due to the windscreen seal failure allowing water to pool. Blower fan is a major issue, but he makes no mention if it.

I have seen the OM617 in this model beat the early W123 cars. Not until the turbo engines were these cars beaten. You should be able to source replacement engines easily from the late W116 and early W123. Body parts are getting harder to find, but there are ample examples in junk yards across the nation.

As for using it for a grease car, I would not. Why spend all the cash to install WVO and dual tank systems, when that will destroy the engine? I find "grease" cars a plenty in the pull a part yards. Injection pumps are destroyed, engines coked up from the sugars in the veggie oil that fail to burn. Injectors get gummed up with them as well. Grease also makes terrible fuel in your location from around October to April.

Better to use BioD in that engine, as well as changing the lubrication to Mobil 1 or another synthetic. That will increase lubricity for moving parts, increase cetane, and extend the life of the engine. I tried cooking oil for a while, and had to clean the whole fuel system of contaminants from the tank to the injectors. The fuel filters were plugged with all the garbage. I should have passed the stuff through a 4 micron filter prior to allowing it to enter the tank.

Just my $0.02

I agree, bio is a better all around fuel to use without having to constantly fiddle with what should be an almost maintenance free engine type.
