For starters, here's a link to the 335i at CarMax and the 2007 CLK550 at a MB dealership. This other place has all the BMW's and Mercedes to go over so I'll be visiting all three places tomorrow morning and hope to decide after test driving a few of them. Keep in mind my limit is $19K out the door.

The C classes have to be at least 2012 as I've noticed the 2011 and older have that cheap looking center dash that I don't care about.
