If you've been a fan of muscle cars, I assume you like simple things. Big motor in the front, power to the rear, a lot of tyre smoke and a wide grin as you rocket off the lines. This is a fairly clear-cut mantra that works for the most part of the year - right up to the point where it rains or snows. You see, muscle cars are notorious for letting the rear wheels be naughty. A splash of rain or ice, and the Mustangs, Camaros and the Challengers of the world are wiggling about, struggling to lay all the big horses down.
