Looks like everything swings towards the 300SD, value for money wise.
The '83/84 300SDs actually look so similar to the later ones. Except for a few body panels and the headlights.. but I'd swap them w/ the Euro ones anyway.
Everyone in Indonesia craves the AMerican style headlamps.. i bet it aint gonna be hard to bring the headlights when I go back and ask for a swap!
Tranny/AC/paint. Why not engine?
You're right.. there's almost always a 300SD on EBay, and in those class ads..
