Your link didn't work for me, but I picked up a non-running (needed an in-tank fuel strainer and some TLC after sitting 2 years garaged) grey market '85 380SEL for just under $300. Had it running in under a week (working on it after work), then changed out the chain & guides. I've been driving it for about 2 weeks now...
Don't get me wrong, it's still got gremlins, but that's why I bought it.
