Odometer misalignment, TMU, and the mechanical flip

Mercedes-Benz W123 · buying

Misaligned or 'crooked' odometer digits are a recurring flashpoint. Some bidders read them as evidence of rollback or a TMU car, while experienced owners explain that these mechanical odometers naturally misalign just before a digit rolls over and self-correct within a few miles; broken plastic cogs are also common.
