I know about West Oxfordshire Motor Auctions and a couple of specialised dealers in the U.K., but anyway, I'm looking for left-hand-drive. I know about Ventes Domaniales in France, and about Zoll-Auktion and VEBEG in Germany. Can anyone help me with similar websites for Austria, Belgium, Denmark, Finland, Greece, Greenland, Iceland, Italy, Liechtenstein, Luxembourg, Monaco, the Netherlands, Norway, Portugal, Spain, Sweden, or Switzerland? France and Germany too if websites exist other than those I know of.

Well a sure place to get a great cars would be from auctions, like http://www.carauctiondeals.com , they have thousands of cars old and new on auctionGood luck finding a good car

In Switzerland, every Canton (e.g. province, state) is totally independent in this question and there is no central sales organisation.Actually I don't know what happens to ex-police cars, either they are converted to cars for "normal" usage or then they get sold to other countries.Only military vehicles are sold once a year in a auction in Thun/Switzerland, see the link.
