Then I found just the place for you!
We drove by a lot named Germantown Auto Sales. They probably had 40 vehicles on the lot, and at a minimum 80% of those were Beetles and Monte Carlos.
When I was younger a dealer in this same location always had a few air cooled VWs on the lot. It sat vacant for years. Based on the current inventory I wonder if it was reopened by the previous owner’s son.
I’ll share a link to their webpage in the comments (stupid Kinja) but they don’t list anything close to all the Beetles and Montes they had.
