You know, I was at a show last summer, one of those "anything goes" shows without a theme, and I spent quite a bit of time talking with a guy who was showing a 1973 Pinto station wagon. Probably the same metallic brown you were talking about. He was the original owner, and it is still an original "survivor, I guess" car... he really hadn't done anything to it other than keep it running. It definitely wasn't in perfect shape, but I was just astounded that a Pinto was actually still drivable after 40+ years. It was very similar to my first car, a 1974 Pinto wagon in the same color. Mine didn't even make it to 8 years old before it basically fell apart.
And... the kicker: he's turned down 5 figure prices for it. I never, EVER thought I'd see the day that a Pinto wagon would be considered collectible. I guess that's kind of true for a lot of cars, but... a Pinto?
