2003 Mercedes-Benz M-Class ML500 AWD 4dr SUV (5.0L 8cyl 5A)
The 500 gets even better mileage than the ML430 that it replaced. The tranny is better and more responsive. Xenons, rain sensor wipers, electric rear quarter windows, folding mirrors, etc. . . . it offers all the features you'd want in an SUV. Lots of cargo space, and tows like a champ.
The engine. It is the best powerplant there is. Wide footprint with 275s on all four corners. With good tires it stops quickly, even in the rain.
