Can you name all the cars this classic Porsche racer overtakes?

Trust us, this isn’t a replay from Forza.  It’s an actual person, in an actual (really expensive) race car, slicing past competitors round Laguna Seca like he’s playing a racing game on ‘Easy’.

Said driver is Porsche racer Leh Keen. Keen has previous of overtaking many, many people for fun, but this footage comes from the recent Rolex Monterey Motorsports Reunion, held at the hairy Californian race circuit now officially know as the Mazda Raceway Laguna Seca.

Driving one of the ten 1977 factory Porsche 934.5s, Leh’s mad skills see him cruise past most of his competition on the opening lap.

So here’s your challenge for the day: the first of you to name everything Leh sees off before the 2m15s mark, when he suffers clutch trouble, receives one shiny, not–transferable internet point.

Grab a pen and paper, turn the sound up – remember, this is an era of motorsport fuelled not just by booze and fags, but by wide arches and noisy side-pipes too – and make notes while reveling in the glorious, glorious sound of the Seventies…
