From the “Cars that need no introduction” file, witness the M5. So ingrained into the halls of automotive Valhalla is the M5 that it seems as though there was never a time without one. Yet while there were fast sedans that predated the Motorsport 5-series, the reality is that this was the blueprint which all subsequent fast sedans (tried to) emulate.
If you look up “benchmark” in the dictionary, the M5 should appear as an alternate definition.
But enough of the hyperbole, hoopla and heady praise. You know the details of what makes this car great. So what makes this particular one special?
