We bought our certified-pre owned ML a year and a half ago, We also purchased an extra year of warranty and 3 extra services. My wife raves over this car each time she drives it. It is the most comfortable car we have ever owned. She loves the commanding view, the ride, and the comfort of the seats. We got the model with the Harmon Kardon sound system. It is the best sound system we have ever owned in a car!
Looks great, both interior and exterior. Plenty of power, especially once up to speed; not as much take-off power, but I was spoiled by owning a BMW 7-Series before this car, and it had a larger engine, to be fair. Ample storage space in the back, and plenty of leg room in the back seat. Interior and exterior trim lighting are unique and attention-getting. Navigation system is impressive, and lots of places to plug stuff in (USB ports, etc.). Not quite as sporty-looking as a BMW SUV, but has a more refined look, and has everything you need, or could even want.
