Car when running correctly was wonderful, but had it in 11 times for major problems, 0 rings replaced twice, two fuel line leaks, transmission went out, and on and on. Lots of keyless go problems. Mercedes would not extend warranty for me. Dealership was very good in handling these problems, but Mercedes would not stand behind product
Very quick, gas mileage good, but not quite up to projected ones especially in city driving. Very comfortable and responsive.
