Well, it's a "no reserve" auction, so the final price will be determined by what two individuals are willing to pay for it. That sort of decision is very, very personal, so who knows? Last time I checked, they weren't making any more of these.
I see from the description that the car, "recieved (sic) its first 800-1000 mile inspection at Mercedes Benz of Kundendienst , Germany 1984". I guess I'm not familiar with the town of Kundendienst - I thought that was German for "customer service"!
