Wanted the new SLK350, but not enough to wait for it, so I settled for a 2005 C320 4MATIC (back in August) and saved a few $'s. It's a good solid car - relatively comfortable, drives well, brakes exceptionally evenly/smoothly. Looks nice in metallic silver with the ash interior - seems to shine a little bit brighter than most other 'silver' cars (of which there are too many these days). Quality sound system. Limited back seat room when taller front seat passengers 'move 'em back'. Generous trunk space. I've had better AC systems in less expensive cars; the center arm rest/storage console is a strange size, limiting its uses. I'm happy w/the car, but not blown-away. Kind of expected to be...
Cool key; quality of audio speakers; smooth acceleration/braking; classy/attractive exterior.
Glove box and other interior storage s/b sized to accomodate more commonly stored items (e.g., CD cases); easy iPod/mp3 connection (currently being offered by BMW and others).
