@Ingo: If you can tell me more details of the former LÜN-hearse, I can try to find out if the plates still exist. It´s quite likely that I know the current owner.

Regarding other abandoned plates: I keep my eyes open. Here are very few cars out and about, still carrying the old "MT" plates. Once I get one of them, I´ll let you know.

Oh, and VW Caddy... Yes, there were in fact some of them, but they all were hideous.

@CarChasesFanatic: So I guess a Spanish, Bergadana-bodied Cadillac will be fine?
