I love the V8 AWD, the few thousand is worth it for the AWD option if you are in snow states. Also the magnetic ride control with the available option of riding with performance or touring is great. I love the navigation, once you get it down. it is quite user friendly. Definitely luxurious with the diamond white pearl and the cashmere interior and light brown wood grain! Great sound with the Bose speakers also! HID lights and LED tail-lights. This car is perfect!
all of them, power & luxury.
maybe a little more back-seat space and rear shade like the Mercedes. iPod hookup would also be nice!
