What up buddy. Welcome back to the NW. I would lean toward the e39 M5. Can't go wrong with the performance, looks and style. I am a fan of the 540, stick around and maybe you can buy mine. Love the 550, but have never driven one. The 7 series is too big for me. Drop me a line. I p/med you my phone number.
Congrats on the graduation. I am having some friends over to watch the Giants for the Superbowl if you are interested in coming by.
