So i got my Xm installed today and was driving around town when i catch a light and i come behind a z4 which is lined up w/ a new mustang, in the z4 is an old dude, and in the new mustang a girl was driving (who was kinda young). So i think there gonna go off the line so i get ready to chase them. The light turns green and the mustang takes off and the z4 keeps pace, about 2 cars behind, so i get up next to the z4 and the old guy gives a look and we both go and catch up to the mustang, overtaking it on the ramp to 95. All three off us get up to about 120 and then the mustang backs off then we slow down, then she comes back up and tries to pass us. We both stayed in front of her till we hit 130mph and then she backed off for good. The older guy in the z4 and I take turns playing around I'd go first and then he starting the race, but everytime if i was behind him i would pass him, or i would pull away. We took it up to 140mph or so and when i got off the exit about 10 miles down the road he gave me a thumbs up and i got off. All the while listening to Mozart.
