BMW tv have just released a new promo for their M5 Ringtaxi. This is the cab where you pay your cash, strap yourself in and get a very, very wild ride around one of the world’s best stretches of tarmac—the Nürburgring Nordschleife.

This is the gig that helped launch Sabine Schmitz into the blogosphere as probably the world’s most famous female cabby. For a closer look from inside the cabin, take a look at the previous AUSringers post from June this year. For more information on how to get yourself a seat in this wild ride, take a look at the BMW website.
