Autoexpress rightfully calls 3 the magic number for BMW. It's BMW's top selling model and has set the standard in the small-medium sports sedan class for decades. As such, any new 3 series model is always big news and the natural question to come to everyone's mind is how it compares to its most direct rivals - traditionally the Audi A4 and Mercedes Benz C Class.
No surprise, the F30 comes out on top as it has in all the comparisons so far. See the full details/results at Autoexpress.
