We've heard the sound clips, we've seen the quality of the interior, heard how steering feel is great and communicative with the hydraulic steering and how it all improves on the E60
We've read the countless other reviews from reputable reviewers, Motor Trend, Chris Harris from evo, etc. I'm pretty sure the outcome of this won't be replicated in other head to head comparisons.
I want to see a drag race, a track race, a Nurburgring run and a RS6 involved before I accept the ///M5 is not again proclaimed the benchmark in it's class.
