Update: Just returned from driving a barely used 2012 C350 Coupe. Car has 11,000 miles on it, it is silver with grey leather interior and walnut wood trim. Not a mark anywhere on the car, it was flawless. It had the panoramic sunroof, 18" AMG sport wheels, nav system, the works. My son and I took it for a spin. The car is comfortable, smooth, has excellent brakes and that 3.5l V6 is plenty powerful. It also makes nice noises. I didn't floor it but I was pretty close and it accelerates like a small V8.
Brakes are very touchy and they haul that car down quickly if you jab them too hard. They are very powerful.
I took it on the freeway briefly and it is quiet and comfortable. You could soak up freeway miles for hours in this car and I'm sure it would be fun in the mountains too.
Anyway, I loved the driving position, seats are excellent and comfortable. Interior is quite attractive and fit and finish was what you'd expect from a Mercedes-Benz. I liked the thickly padded steering wheel which telescopes and adjusts up and down at the touch of a stalk under the steering column. That panoramic sunroof is really nice too, it opens up the entire cabin even the rear and if you want to cut out the sun there is a one touch retractable shade that runs the length of it.
I played around with the nav system a bit and the voice commands work pretty well. Didn't have my phone with me but the saleswoman had her iphone and it synched up easily via bluetooth and we quickly had her playlist blasting through the Harmon Kardon sound system.
They are asking $38,900 for it... I am tempted. No pressure at all at the dealership which I like. My only hesitation is my commute. I put 15,000 miles a year on my car just in commuting and this thing requires premium fuel. I could realistically expect comparable mileage to my Maxima... which isn't great. Maybe 22-23mpg on my commute.
Oh, and it does have auto dimming mirrors and fold down rear seats.
It basically looked like this, with the same 7 spoke alloy wheels.
