2002 Mercedes-Benz M-Class ML500 AWD 4dr SUV (5.0L 8cyl 5A)
Safety, performance (fun to drive), all weather drving capability - wonderful vehicle.
Maintenance costs on the other hand are unacceptable for a vehicle of the this class. Problems, you bet - 4 rear main engine seals in 96,000 miles at $1,300 per repair, front lower ball joints at 25,000 miles, engine oil leaks, interior plastic trim pieces breaking, $775 for brakes every 22,000-25,000 miles, three door panels repainted - rust problems, $1100 to repair ventilation system, and many more.
Handling - very good for a SUV though sway bars are a little stiff. AWD drive system is great for Colorado weather. Engine and transmission are smooth and powerful - this SUV gets going and it weighs over 5,000 lb!
Just find a way of kkeping the vehicle out of the shop - way to expensive to maintain and repair.
