I tell ya, I am SO glad I sold my '67 bug before the bottom dropped out!
*Whew!*
Are you talking about the actual bottom of the car ..... or its selling price?
I would think that if it was a 67 VW "bug" and in good condition, its selling price would be going up considering the increased costs in gasoline and insurance.
I once owned a 66 VW "bug", Model 1600, that I bought new for $1,600. I loved that car, except for the windshield defroster.
