Sergio,
Your vehicle is a monster. I really got to see them put through their paces at the M5 Launch in Spain. We assembled in the underground garage to pick up the M5s and all of the support vehicles were X5Ms and X6Ms. For the first day the weather consisted of a heavy downpour to start and became progressively worse. The X5Ms and X6Ms took off as if it were perfectly dry and the hounds of hell were in hot pursuit. I followed them in my assigned M5 from the hotel and had to screw my courage to the sticking place to keep up.
When we finally reached Ascari I was mentally drained and full of newfound respect for the X5M and X6M because prior to this display I didn't fully understand the concept. Call me schooled.
Again, great to meet you and I look forward to returning your kindness.
Cheers-Milton
