It's a buyer's market right now -- you won't have trouble finding a nice car. Twenty miles in eleven years is a red flag. "Complicated" paperwork isn't reassuring either. If I couldn't see it myself, or have a trusted co-conspirator see it, sit in it, and stream a feed to me, then I would pass. A 20 mile engine hasn't even been dialed in yet, so it would be hard to tell on a quick drive whether it was a crappy build or one that just needs the carb, valves, timing and plugs played with... especially if the gas is ten years old.
