I used to drive a mercedes C230. I recently made a switch to the IS 250 Lexus. The car drives and handles excellent. The road noise was much less than the BMW 3 series and Audi A4 I drove. The interior is about as nice as I could find in the market and the car has not had any problems. It feels more like 240 horsepower even though it's rated less. It's very fun to drive. They really built a great car with the new IS. I'm never driving anything but a Lexus ever again.
Heated and cooled seats, 10 power adjustments for both front passengers, mp3/ipod port, 6 disc cd changer, smart key technology, navigation is way easier to use, back up camera, bluetooth, heated outside mirrors, LED interior dome lights, xenon headlights.
Maybe a little more horsepower, but it's plenty for what I need and the gas mileage is better.
