Note the Drivers Education stickers. Most (all?) Mopar driver's ed cars where white. I've seen white '70 GTX driver's ed cars, and white '68 Coronets. It's quite possible the stickers were removed from Roger's car.
And white '70 Chargers? Roger knows of two, both without boxes. One he saw at a toy show in Toledo years ago, and it was missing the exhaust tips. He saw a photo of the other, which is in the hands of a collector. Anyone else have one?
