I just bought an '83 300SD with 535xxx KM's/332xxx miles two days ago. Gold exterior, motor runs well with little blow by. Plenty of power. Transmission shifts nicely, fluid smells and looks decent. It sat for a while under a cover, and I think the PO might have been the original owner (I didn't ask specifically). Just washed the engine today. I'll find out if any of the messy areas have any actual leaks. Needs new belts and possibly some injection work, since it doesn't like to stay running when it's right cold. Not perfect, some little rust spots, but she's an old beaut, and for $900 you can't go wrong!

It's replacing an '88 Corolla wagon that I got a $1000 insurance payout on after I got t-boned and it was totaled three weeks ago. Not too shabby!
