I think I still have a Magazine from the U.K that has this Aston Martin Lagonda shooting brake in its pages. Most of these cars are custom coach built.I've seen too many road-railers to think they're weird - the Unimog and Land Rover ones are more normal than most!

Do you know any more about this one? It's a bit different at the rear to the one Roos Engineering did.
