Have had this car for 3 weeks, and can say I am thrilled with everything about it. It has a drive quality unlike any other vehicle I have ever owned and that includes 3 Lexus'. The interior is extremely well designed and luxurious, standard sound system rocks, and the quiet soundproof cabin combined with the smooth, and I mean smooth, drive makes this car unbeatable. I test drove the Lexus IS250, nice car, not as solid as the MB and the BMW325--no comparison. There's nothing about this car you won't love. It gets compliments everywhere I go, I have the black/stone. I can't say enough good about this car. No manufacturer can compare to the Mercedes in buttery smooth, solid, quiet ride.
Heated seats, stereo, interior design, handling. Perfect from bumper to bumper.
Gas mileage is a bit of a disappointment for a car this size. I'm getting 18 city and 26 hwy, actually got better on my '04 Lexus RX330.
