If you're looking for a sporty drive, go with the 350 or G37.
If you're like me, the lead in your foot has been replaced by maturity, this is a great car for you.
Bought this car 15k miles ago with 35k miles.
It is my first "luxury" car but I've driven all the competition (bmw, g37, tl, c300)
Comfortable, looks great, feels great, and the nav makes life easy.
The interior is a tight fit so if you are using the back seat all the time for passengers, pass on this one.
But if you only use it on occasion then the back seat will do.
If you're sitting in the front you'll be comfortable, you'll be pleased with the look of the interior, and you'll find the touch screen easy to use.
Looks great, both from the inside and out.
It's a smooth drive and comfortable (as long as you're in the front) on long drives or as your daily commute.
The Nav is super easy to use with the touch screen and the ML radio sounds perfect.
I haven't had any mechanical issues so far in the 15k I've had it.
Power and Ipod.
As mentioned before, if you're looking for something powerful, you're better off with the 350 or the Infiniti.
Press the gas and you won't experience whiplash, or even slight neck pains.
It would be nice if you could control your ipod from the radio controls on the touch screen, rather than the wires showing (audio jack in the center arm rest).
Bluetooth control would be better.
Another downside, expect that maintenance will be expensive.
Tires won't last long.
