We are renting one of these while on vacation in Park City Utah. This thing has 479HP and is an absolute beast on the highway....So damn fun to drive. Make the engine in my 550 feel like a 10 speed bike!! We've owned a 330, X5, Z4 and an X4. This is the first V8 Beemer i've ever driven and it may be the fastest car I've ever driven. I wouldn't be upset if my wife decided to trade her 460 for one of these...
