just to finish this thread off, and hopefully help someone else out, I learned something
Nobody rents cars for one way cross border trips in Europe. So much for the "Common European Market" where borders don't matter.
I contacted a specialty high end sportscar rental company who never called me back so I tried a couple regular car rental places and they would not book it. Wonder if I could book a round trip and just return it in another country? I've noticed German rental cars have some kind of official documents in the glove compartment, must be country specific laws like that. I probably would not even be allowed across the border.
When I mentioned this idea to Europeans when I was there they thought about it and agreed saying they would never do a 14 hour one way cross country drive like that, they would take a train. And because they would not drive it, the car would probably never make it back to the home country.
So I flew and spent the extra time in the hotel room catching up on Car Porn. I love me some European Car Mags. Notice a theme? You'd never get that much Porsche ink on one shelf in the US and this was just a small place in the airport.
Oh and I did get to eat a Mercedes Benz sandwich. Talk about crazy brand extensions. . .
