it all depends on your definition of fast...
all BMW's are top end vehicles... they are tuned for maximum torque around 4500 rpms...
so if you want 0-60... you might not want one... but from 60-130, you definitely do!
as for the pathfinder... lots of low end torque, but not fast off the start. great from 40-80, but a real pain to get to 100.
