As a regular front-runner at the daunting Isle of Man TT races, it takes a lot to impress legendary motorcycle racer Guy Martin.
However, it seems that the world's only road-legal Ferrari FXX more than fits that bill, judging by Martin's reaction in this video, filmed at a recent Supercar Driver event.
Despite being better known for his two-wheel exploits, Martin is a die-hard car nut, having owned a BMW E46 M3 CSL at age 21, following that up with a Porsche 911 GT3 RS, an E92 M3 and then his dream car, an Aston Martin V12 Vantage.
With no telemetry, it's unclear what speeds Martin manages in the screaming V12 hypercar, however judging by the uncomfortable looks on the face of his passenger, as well as his own deep concentration, we'd say it's plenty.
"I've been in fast things, right, I have never been in anything like that - I'm shaking" he says after his brief run.
What a car, what a legend.
