if you are gonna be on the track go with a cbr or r1. very much more of race bikes. gixxer and zx10 are great bikes as well, just a little more neutral feeling probably a little more forgiving.

i say 550 and i drive a 3-series. .... they are just great cars.
you wont regret it either way but the 5 series seems like a better choice between the two.
At least as Americans, we are not pompous enough to put "great" in front of our country's name. I mean honestly who gives you Brits that designation. (not serious)
