Guy in a 2008-2011 S63 AMG was tailing the shit outta my car (2014 650i GC) all the way up this access road (in mexico), right as we turned to get on the ramp for the highway (it's an uphill on-ramp) we both pounded it (I was in front). Pulled probably 3 car lengths on him before I slowed down and merged -- and I shifted early on second gear too (around 4500 RPM).
I went home and ordered the BMS Stage I for my car. Can't wait
