I met a friend of a friend who lives in the midwest. He's the owner of several BMW's (Millionaire, retired) and loves just going to auctions and buying bimmers at a great price. He's going to shop around for us

Now my selection will be a used 540i and I'm going to tell him to keep an eye open for a nice used M5 but I doubt the M5 will be in my price range.
