 I own a Toyota minivan. I have tried Lexus Rx and GX 470, BMW X5, Toyota 4-RUnnner and Highlander hybrids before I settle down to this ML 320 CDI. All the Toyotas and Lexuss have the similar driving trait and characteristic, includ quiet, comfort but boring. BMW is impressive for its road handling and driving capability but it is louder and coarse. Its electronics is too complicated with a lots of trouble. The Mercedes combined all those goodness plus the advantage for fuel economy. So far I got 22-24 MPG combine local and highway in the break in period. The truck is more comfort and quieter than Lexuss and Toyotas. The road handling and drivability is definitely better than Lexus and Toyota
