My amazing 2007 Mercedes c-class.
This has been the most reliable car I have ever owned. It costs more for fuel and oil, but I have never needed anything else (besides windshield washer fluid). I love the controls for the radio on the steering wheel and the heated seats are awesome. It also has dual heat and air conditioning controls for the driver and the passenger. It has a memory for where you like your seat and adjusts automatically for you. All in all I have never been happier with a car.
