That's a lot of money for a 5 series after having one for a loaner car.
Besides that though, what you just showed was an M6 costing 10,000 euros more with 22,000 more km on it. I'm also guessing gas mileage is more heavily weighed in Europe.
I can't imagine a cop hanging out in the first sport. I don't even know where a cop could hang out on on Mockingbird; it's a fairly busy road with no shoulder. They were gunning radar/laser from the side of the road?
