Yesterday my mom test drove the new 5 series. She test drove the 545i, which she liked a lot! She currently has an E320 with 4matic. We then went over to MB and test drove the e500 with 4matic. She liked the power of the BMW but HATES the technology. She was saying that it is way too advanced just to put the car into drive, I was like thank god you are not looking at the 7 series. The E-class is as simple as they come and she knows the product. What would you guys choose? I know it is a dumb question on a BMW forum, but I am interested in seeing what you guys have to say! I am really pushing for the BMW because I have one, like it better than the MB's and the quality I think is far superior to MB especially after I have seen the sh*t that car has put her through. My 330ci has not given me an ounce of trouble!
