Hi, I am planning to lease a new BMW 430i Gran coupe and got couple of good deals. I want to keep my monthly payments to max $500 with 0 down. I am seeing couple of options which are listed at a price range of 50k and 46k. Also, I see few 430i xDrives listed around 43k and 45k. I live in San Fransisco Bay Area. Will buying an xd make a difference.Can anyone help me out?
