A friend of mine is trying to decide which of these two cars to lease for 3 years. They are quite similar in price, with the main difference being the Merc comes only with an automatic, whereas the Bimmer has a manual which he prefers. He drives about 50 miles per day, mixed interstate and 2 lane backroads. I generally prefer Mercedes over BMW, but in this case the 3 series seems to be the nicer, and more fun ride. How do you feel?
