The car is solid, goes like mad and is a blast to drive. The V8 is a hoss, smooth and has lots of power. The balanced handling is also incredible. It is hard to believe you are driving such a big car. No reliability issues to speak of yet. The car sucks the gas if you drive it - not much of a surprise there. The stereo is also very good and feature list goes on and on. Sport package is a must. Mine has no GPS but I don't know if it is necessary - less to worry about breaking.
Handling and straight line acceleration. Fit and finish (exterior and interior). Good looking exterior design.
Weird rubber tie downs in trunk. Annoying problem with LCD below the odometer (some rows of lights don't light up). Bad brake dust on wheels.
