My '75 300D has cannister fuel filter, '76 had spin-on. Worse thing about W115 is changing oil filter. Must be done from below and at a convoluted angle. Oil spill required. Air and Oil filters have always been hard to find.
Tighter turning radius than W123, not as quiet or smooth a ride but fun to drive. Nice uncomplicated heat/AC controls.
Have a '75 300D (black) which needs steering work, but engine starts right up and runs good that is for sale. Body in good shape for age. Not street driveable until front-end work done. Needs new tires. Email me if anyone wants more info.
Asking $500. Central Alabama
