Heated seats and the power rear seat were uncommon options on the W126 diesel. No diesels ever got the city / country horns. The roller blind was optional on the 350s, as was the auto leveling rear suspension (rare). 350s do have a leather steering wheel and shift knob standard, as well as the rest of the nicer updated interior.

Most diesel W126s are "basic" models with no extra toys, just the standard power memory seats, automatic climate control, and automatic antenna.
