I was skeptical with the reviews and don't listen to them. This is a luxurious SUV and fun to drive. I previously owned a Lincoln Navigator and Jeep Grand Cherokee Ltd. This is a much better SUV. Diesel is smooth, quiet, clean and gets 20/25 mpg. Ride is exceptional and corners like a sedan. AWD is noticable only when used, not when turning. It hauls a boat effortlessly and has great low speed get up and go. NAV/radio and Bluetooth work great. I have experienced 0 problems and it goes 550 miles between fillups. I highly recommend the ML 320 to all. A nice looking SUV and a lot of car for the money.
The diesel engine is quiet with no black soot like older diesels. It offers 19-20 mpg around town and 24-25 mpg on the road. 24 mpg at 75 mph and 25 mpg at 60 mph. Bluetooth is a must. NAV/radio works great, much improved over older models. Ride is smooth and 7 speed transmission is exceptional.
Leather interior should be standard in a MB. Offer an XM Radio option. Still needs a third row seat option.
