i am new to this site.raised a poor country boy in macon ga. i loved diesels as far back as i can remember.my frist ride in a mb was 30 years agoand i was impressed.i never thought i would ever afford one.recently i retired and having time on my hands i bought a 1946 [my birth year!]chev 2 toon truck to tinker with.i decided to take out the 216 cu in 6 cly. and install a diesel.this week i found a 1985 mercedes 300sd and bought it as a doner car. i drove it home and love it. i got it dheap cause it would not shut off with the ignition key switch.i had to open the hood to do something to shut it off.it is automatic.
