 The X5 is a great Sport Activity Vehicle.  It is a bit on the expensive side compared to Ford, Chevy and other big named SUV manufacturers, but they aren't as thrilling to drive as the X5.  Performance is spot on, like many other BMW's, and the new Twin-Scroll Turbo provides even more thrills.  Coming from a 335xi (Twin Turbo) the X5 provides the same excitement during driving that the 335 did. Also the interior space is massive, and provides enough comfort for me and my occasional passengers.  I do not regret this purchase.
