Automotive Forums  Where Car Enthusiasts Go to Discuss Cars Online

Hi,

I'm looking at several options for buying a new car. I'm looking for a 2006-2007 car. I'm considering the following options:

Mercedes-Benz:
E350 (2006/2007)
SLK350 (2006/2007)
CLK350 (2006/2007)

BMW:
525i/xi (2007), 530 (2006)
Mini Cooper S Convertible (2010)
Z4 (2007)

Lexus:
GS (2006/2007)
ES (2006/2007)

Audi:
A6 (2006/2007)

I am looking for a car based on the following:
-look
-reliability
-visibility
-comfort
-performance

Out of these which one seems to have the least problems? Are there any reoccurring problems with any of these cars I should be aware of? If you had a choice, which one would you buy, and why? Are there any better alternatives? I'm looking for a luxury car that is around the price range of those cars above that is fun to drive, considerable reliable, and comfortable. I prefer the look of Mercedes and BMW over Lexus and Audi but I want to keep the options open.
