Here in the UK there's a consumer magazine called Which? that reviews just about any object or service you can buy.
Anyway in their 2012 Car Survey they have concluded that in the 'Large Car' sector, the new F30 3 Series is the Best Buy (fine handling, performance and refinement plus class-leading fuel efficiency). So, everyone give yourself a pat on the back for being such canny buyers
Incidentally, in the Used Car section the 2005-2011 3 Series came top too, and in the 'Best Car Brands' BMW came 4th out of 29. Better not give too much else away or I'll have them hounding me for copyright
