I'm in the market and cannot decide between the A6 4.2 and the Benz E350 4 matic. I have a 03 C320 4 matic and love it but the reliability comments I hear about the E class are making me a bit worried about spending 55k for this car. I've never owned or no anyone who has owned an Audi and I've read comments the past A6's were not very reliable. What's the deal here with both of these cars reliability? Lastly I would like some feedback on deciding between the two. Is there a hands down winner here?
