Rare or not?

340 darts are rare around my area. there used to be one in a nearby town, besides mine, but I haven't seen it in 20 years. It was Plum Crazy, with white bee stripe. The person who owned it, it was rumored that they owned it since new, and drove it for twenty plus years. The car sat in front of their house, quarters rotting away, but it was a daily driver. Wonder what happened to it.....
