1. Lexus LS600hL

2. Mercedes-Benz S63

3. BMW 760Li

4. Audi A8 L

This is just my opinion. All of them are great cars, and I like them all. So I'm not putting down Audi by placing them at the bottom.

Honestly, before the new 2010 BMW 7 series came out i probably would have said the Mercedes-Benz S class or the Lexus LS but if your referring to the 2010 models then id have to go with the BMW 7 series. The BMW will always turn heads and state success. Exterior features are more captivating then those in the Lexus LS or Mercedes S class. The BMW has captivating Angel/Halo lights, Linear LED tail lights that look like horizontal lazer beams. Everything about the car screams luxury and "look at me". Don't get me wrong the Mercedes S class is a respectable luxury car but they have become way to common and overrated. The Lexus Ls is to simplified for being Lexus's flag ship luxury vehicle, sure it can park it self, but its a forgettable car. The Audi i feel hasn't reached the status-quoe of other dominant top of its class luxury vehicles. Yes the Audi is a nice car, but id take the 2010 A4/A5 over the Audi A8 any day. So in conclusion id take the BMW 7 series. This is of course my own biased opinion, BMW's and Infiniti's run in my family so Im more likley to lean toward them.
