Do you know anyone with a dealer license?

If not, you should be able to hook up with a smaller dealer that sells typically 1 to 3 year old luxury cars. Chances are that the dealer gets them from the dealer only lease return auctions. You should be able to make a deal with them. Some can even get you into the auction, while posing you as a dealer with credentials. They typically want either a flat fee or a percentage of the price (5 ro 10%).

The Hi-Line auction in Riverside is the best one in So. California, but they have them all over the country.

Most dealer have access to the dealers only part of http://www.manheim.com/ website, were all cars are listed that come up for auctions, including the history for what cars sell. This is the primary tool all used car dealers use.

Most Mercedes and BMW lease return MUST be sold via auctions. Dealers are mostly not even allowed to take lease returns back and sell them directly, they must go through these auctions.

These auctions are also a lot of fun. When I went I had 2 hours to look over 3000 cars, of which 600 were Mercedes.

When the auction starts things move very fast and you better be ready to bid. Each car bids away in about 5 to 10 seconds.

Good Luck!!
