I love my SUV, I cannot believe I was able to afford such a luxurious vehicle. The design inside and out is so extremely comfortable and breath taking. This vehicle has everything and more than I could have ever wanted. It drives like a champ especially in the Miami, FL rain. FYI: I would not change the locking system, because if you ever were to go into a canal you don't want those doors locking automatically.
Navigation, DVD player, memory seats, digital temp., interior space, quality leather, sunroof, puddle lamps, horsepower, EVERYTHING.
Maybe push start engine but not neccesary. Maybe XM radio but I would not subscribe. Therefore NOTHING NEEDS TO BE IMPROVED.
