I also would love a Thing.
There was one up by West Chester in the early 80s. It bore a vanity license plate that read "THING."
One of my sad memories is of getting onto 202 heading for the Denny's and seeing a VW Rabbit with the "THING" license plate on it.
What I really want is an Opel Manta. Four Speed. Any model year from 1972 to 1974, although I'd prefer the '72, and the RallySport paint job.
