I got a question for anybody who might know. I did get a brief encounter with a bmw 645 or 650, didn't get to see the rear, but we were rolling side by side at about 40 mph and both decided to stomp on it and test each other. I started pulling on him slowly before we both seperated and went our different ways. Are those capable of beating a srt-6 or was he not trying? Also I had my 300+ lbs brother in the passengers seat so that slowed me down and he was by himself. This was a brief encounter maybe a quarter of a quarter mile. My one sorry story, don't that suck, lol.
