Meh it was OK I wouldn't buy one. Not a very interesting car. IMHO an E class is as low as a decent MB goes. Also the 2010 ML350's are horrible. They feel like a minivan you buy your wife to run around and get her hair done. Not a proper MB truck, well at least compared to the G. OTOH the C was better than the ML I was a decent little car.
A C63 AMG would be interesting.
I think we averaged 8mpg.
