I love this vehicle! Also own an '02 C240 & an '06 ML350. This is an all- out luxury people mover! Comfortable and roomy front and 2nd row seating, 3rd row is great too if you're 6ft and under. Performance is very good, and is great if you learn to use the "finger- shifter" on the steering wheel. Very fun to drive short or long distance. Fuel economy is not bad considering it's weight and very quiet smooth ride. At first sight some say "mini-van." This is truly a cross between an SUV and wagon...haven't meet an R-Class owner yet who deems this a "MV." The more you look, the more you like. Interior appointments are that of the ML than say a sedan. Clearly Mercedes built!
If you have kids or easily bored adults, get the factory installed rear seat entertainment system. Parktronic is a must, this thing is huge! Reliability.
Better interior appoinments, like that of an E-Class. Driving/Fog lights standard.
