WOW! What a group we have here. Everybody seems to have an amazing background and it's interesting to read about each. OK, here's mine.
Went though three (3) X5's in the course of 18 months

The last one was an '03 4.6is. I am number #16 on the E60 M5 waiting list at the local BMW stealer. I was told they're sold out for the next 2 years ;(.
Phew, I'm done.
