My dad and I tried getting 2 BMW's at once, and possibly a third a couple months ago, but my dealer wasn't really doing anything special or bringing the price down much for buying multiple vehicles. We were trying to get a 10 X5, 750/760 and possibly a X6 hybrid. All were going to be paid cash.
We decided to get all the cars direct from Dubai rather than importing and wait for 2011 for for the X's. My 2011 X5M an my moms 2011 X6 Hybrid
