An om617 will have the same mileage as the m103? Really?

Finding a td is gonna be challenging... I dont care about speed as much as simplicity to own and operate. (if it does 80 on the freeway without killing itself i am good).

I owned a 240d .. my god getting that to 70 mph was a herculean effort. My 300td (turbo) glides at 80mph.


Is it better to hold out for the om602/603?

My final question. Is it still diyable? How much more difficult are day to day items vs the w123?

Thanks
