FYI: 1984 240D replacement engine from OKC Mercedes dealer.
Engine ran for 38,000 miles before the driver seat fell through the floor.

Hi gang...do you think I was being unreasonable to stick to my $1000.00 for a Mercedes Factory crate engine ??

Buyer declined, offering $800.00. I just wasn't in the mood to take it being as I had to lift out the engine and pallatise it too.
