Sweet ride, Jeph ! As always, you have great taste in cars...
I would probably go with a 2004 MB C240 AWD Sedan.
Definitely not as sporty or fun to drive as the BMW, but I would need the AWD up here in the the winter.
My winter car hit 150k yesterday, hopefully I can get a couple more years out of her :
Still waiting to see what you replace the Boxster with ( 2004 911 40th Anniversary maybe ? )
