To get the most, you'll have to do the dog&pony show of advertising in specialty publications. That means tire kickers that always wanted to drive one of those and guys that didn't have anything to do that afternoon. I suppose with a car like that, you'll get that anyway.
Before you even start, find out what it's worth and decide what you'll accept. Might be worth a trip to Hershey or Carlisle, maybe even Atlantic City.
