Since BMW started building cars after the second world war, they have never looked back. The Munich-based firm has made a solid statement in the auto world by being a leader in luxury vehicle brands. This claim to fame has spread worldwide to the extent that one would be hard-pressed not to find a BMW model anywhere on the four continents. BMW, as it is, labels itself the ultimate driving machine in its classy ads. This claim is not mere talk but can be backed by years of delivering solid quality and customer satisfaction. The German-originated luxury car maker churns out many different brands every year but our immediate interest is in the M5 or the Series 5.
