Who are using 2003 Mercedes-Benz S500?

I wonder does anybody actually test drove ALL three models: BMW 750L, MB S550 and Lexus LS470 at the same driving conditions, same test track on the same day? Or you just voiced out your personal thoughts/impressions about these 3 models and speculate their performance? I did test drove all 3 of them in Sept. Pls. see the link below and my comments after the test:

Change to either AUDI A8 or the new S-class! Audi A8 is cool with good features and a good engine, S-class are also good but i think the car is a bit too common, because everyone in HK drives a S-class!

I think u should change it to BMW 7 series because its more luxury.
