 Great driving, instruments ergonomics and logically fits to me 100%. Was so happy with 27.3 miles/gallon in city. Get over 630 miles on highway easy.Have 63990 miles on. Service expensive but they change everything every time I went, so I hoped it would run forever with always new parts placed in. Rear break  burned out; due to excellent engineering I replaced it myself in 15 seconds, bulb costs $.99. But then diesel engine seems to be deal killer. Leaking oil,  damaging intake, $2,500 for repair, need to take engine out. 3 months later engine light announced blue urea heater failure, $2,200. Just to read an error on dealer's computer, plug it in computer - like I just want to know whats wrong - $ 150. My friend has S model with same diesel engine and he needs repair and maintenance for $7,000. My impression is that ML bluetec is a great car with excellent ergonomics and logical instrumentation, shift on steering column I love. But seems too expensive to maintain. I paid over $61,000 for new one, cant even tow anything. Mercedes puts small cooling units and if you want to tow ,conversion cooling kit is $4,400. Diesel was made with torque to tow, right? I am disappointed in the "Best or nothing", as it doesn't last no matter how perfectly you maintain it. Maybe is just my diesel engine choice. This is my first and last Mercedes. Im not that rich to pay for luxury service and frequent repairs where cheapest one is 2Gs. I am sure Mercedes has received bad feedback about turbo-diesels overkilled with emission internal devices, but they definitively let us know and asked premium price for engine that is to fail and shot down anytime.
