Well, from the success I have had with selling my 85' 380SE, I would say about $700 or $800 in VGC. I guess I am going to have to end up giving mine away. I have it priced at $950 on this site and the other MB site and have had no luck at all. It has a solid body, but faded paint.... transmission and interior (MB-TEX) are good. The main problems are all maintenance issues, but still driven to work daily. It needs injector seals (occasional missing), thermostat and the last time that the timing chain was replaced is unknown, so that needs done and probably a camshaft, as it has some lifter chatter. I was thinking before I tried to sell it, that it would be at least worth that in parts.

Guess not... I may have to end up junking it out or drive it until it hits the road.
I know a guy on the other boards that bought a very nice 85' 380SE for like $700.... what a deal that was, but I never get deals like that.... I always pay too much and sell for too little.
Good luck!
