I saw a LHD Milan brown 450 SEL in Freemantle about 4 years ago, with quad lights and Euro bumpers. I managed to have a talk with the owner.
He imported it from the U.S. about six months earlier. He said it was headed for the crusher, but it was far too good to suffer such a fate. He had the car 'given' to him for a nominal amount, and imported it to Oz. The car had spent most of it's life in Arizona, so being in a dry climate, it had no rust, but the paint and upholstery was in less than best condition for age.
The Merc. was one of a batch of four which he had imported, the others were classic American 'big iron' muscle cars, of the late '60's and early '70's.
