What's the rarest car you've seen in the wild?

Not including showrooms and car shows, but just out and about on the road?I saw this 1965 Aston Martin DB5 today, couldn't believe the owner had left it parked near other cars! Looking up the MOT history online shows it has just over 60k on the clock, so I guess it had had at least some use in its 50+ years of life.What rare or interesting cars have you seen actually being used? via /r/cars http://ift.tt/2tCT82Q
