We took our ML320 CDI on a 4 day trip through the winter mountains of Oregon and California. The ML ate it up. Here's why: Full time 4 wheel drive with full time traction and stability control, quiet roomy interior, comfortable seats, a bright sunroof and pleasant interior decor, driving feel of a car and not a truck, and an incredible drivetrain. This very quiet diesel engine and 7-speed transmission make the ML a rocket. You never lack for power. Ever. You want to pass someone? Uphill? Press the throttle and it's done. Here's the best part. We got 27 mpg on our trip!
Power and efficiency of this quiet, high tech diesel drivetrain. The harman/kardon stereo and satellite radio. Good sounding blues anywhere! The optional fully adjustable leather seats. Impeccable fit and finish - this vehicle is made in Alabama, USA.
Completely redo the navigation system. The unit is menu intensive and very tedious to use, therefore I avoid using it. My cheapie portable Garmin nav system is far simpler and more capable.
