Well, here's a 1983 240D with 330k miles. Rusty and hit on the passenger side, everything else is there including the 4-speed.
1986 300E, most interior parts left (for you W124 300D guys), 434k on the clock:
Sorry, no photo of it but a 1984 300SD (behind the Porsche).. wrecked but the drivetrain seems all there, as is the interior. 258k or so:
There's also a W114/5 300D in there. No photo. From memory, the backseat is gone and the grille is gone, the rest is all there and the body's very straight. I think it's a '76 and if I remember right the odometer reads 80k. Whether that's 180k, 280k, 380k, etc, I don't know.
