Agree with NCAMG and alexmish. I went ahead with a 3yr lease on a 2013 50i in December. I was not thrilled with the new look and at the time I was not sure that it would be any larger. I could really use a better 3rd row, especially in 3 years when the kids a older. I almost leased a GL450 but liked the performance and sportiness of the X5 over the additional interior room of the GL.
I will be in perfect position in 2015 to get an LCI X5 if I'm still in the SAV market.
