That is the best car in the world and the most technologic. The Night Vision, Stabilitrack, park ride assist are just some examples. I had a Mercedes-Benz S600 in the past and the confort was too poor and the performance was less impressive that the DTS! Wow!!! Three months ago, I asked to a Mercedes-Benz's salesman what was the difference between this Cadillac and the S600 of Mercedes. He told me : You must be agree to pay 50 000 $ in more !!! I think that I will keep a Cadillac for the rest of my life.
Best things : Too much, but, for example, Night Vision, Rain sensor, Park ride assist, Stabilitrack, Northstar engine, DVD and GPS systems, and I can receive and send all my e-mail!!
