I was here back at that time, I had an '05 E53. Traded it on a Tahoe in Oct 2010. Within the next year I'm getting ready to take the plunge and buy another X5.

Lol, the Tahoe is nearly perfect. Always starts, never has left me stranded, never had a warning light come on. Got me through 16" of snow like it wasn't even there. But darn it, I still miss my old X5.
