Ive got an 08 3.5. For the 08 , the only 2 trim levels for the 3.5 were v6 standard and v6 luxury.

To the best of my memory, the v6L compare to v6 contained differences such as:

SAT NAV, subwoofer , HID headlights (not projectors) , fog lights, sunroof, heated seats, leather interior including steering wheel, gear knob and armrest, different style wheels (still 17").
