Track taxis are used for picking up drivers with problems, dropping off flag men, or giving non-drivers a relatively cheap thrill. If you've got to be a passenger, what's the best track taxi?

We're partial to the BMW M5 sedan, the official track taxi of the NĂĽrburgring. With a 0-to-60 time of under 4.5 seconds and an electronically-limited top speed of 155 MPH, there's plenty of high-speed fun to be had. Add in legendary BMW driving dynamics and you'll have all the g-forces most people will want to endure. Not to mention, you'll be able to enjoy your trip around whatever course in luxury and style, as with any good livery vehicle. If it's good enough for the "Green Hell" it's good enough for us.

How about you? What do you want to be tossed around in?
