208mph? With the lights off? Driven by a 19yo...ok. Makes for a great internet story, just like the guy in the 70's that strapped surplus JATO rockets to his Impala and did like 10hundred miles an hour across the Mojave desert.
Is it possible? Sure. I've seen the newer mustangs hit those speeds without aero at some of the mile events. It'd be interesting to see and hear the kids side of the story and what he did to the car.
