When I had the 335i, the kids at the office with STI's would always want to race me. Besides the one guy who had put on a huge turbo, they all lost to me. I'd always point out that I had the adult version of the STI, and to enjoy the feeling of driving on a broken pogo stick since their ride was so horribly harsh.
XFR is a fantastic car.
Mazda has very quietly started to turn themselves into a luxury brand. Check out the interiors of their current gen 3 and 6. They just need to add the powertrain to play with the Germans.
Speaking of playing with the Germans, my Grand Cherokee lease is up here in a few months, currently looking at a Genesis G70 if I want performance, and the Volvo S60 if I want pure luxury. I find the Volvo's to be simply gorgeous inside and out.
