I own a 2002 C320 (same car as you are looking at)
If you have never driven a Benz, you owe it to yourself to do so. Performance will not be great with the 230 or 280...it will be OK, but not great. if you want performance, drive the 350. I am 6'3" and weight 250 and I have room in the front. if i am in the back, the person in the front has to move up. The older models (2002,2003) has quality issues..mine included, but those have mostly been taken care of with the newr models.
The new interior (2005+) really gives the car a touch of class and I wish mine had it. For those saying a C-Class isn't a real Benz has obviously never sat in one. 8 air bags, traction control, stability control, 5 speed automatic just to name a few features.
