Yes, Barris bought the rusted run down Futura for $!, it had been setting unused in his back lot for years. I don't know about the real Munster Coach, but the real Dragula is hanging from the celing of the Hard Rock Cafe on the east coast. (New jersey ? Atlantic City?)
And as the Futura this car would have never sold for any where near four million dollars.
Funny, I thought the real Dragula was in the Volo museum in Illinois. Besides that, I think all of us know that the Batmobile is an iconic car. I do hope that someone removes the gewgaws that barris added, like the Barris emblem and the Ford emblem and all the goofy labels that were not on the car in the series.
