I think that's the case with this W140 - the dealer didn't know what 'close assist' was (he thought I meant 'central locking'), and when I left a door and the trunk almost-but-not-quite-closed, neither closed by itself.

For the E500/500E, what about big items like timing chains, head gaskets and so on?

And what's the difference between a 1994 E500 and the E500 Limited?
