This is the oldest auto in the world that was sold at auction on the 7th of october 2011. It is a De Dion Bouton et Trépardoux quadricycle built in 1884 and which was sold for $4.6 million dollars at auction in Hershey Pa on the 7th of october 2011 and which established a record.. I have added this photo to my album no. 33. I am limiting myself to exceptional and oldest autos as the subject is limitless.
