Three things you need to know: 1) it's free, 2) it's for the driving obsessed, 3) it's free.

Winding Road is a monthly digital car magazine which you sign up to online (natch.) Besides the car reviews, news, features, and "Hot Cars" section, there's some awesome burnin' rubber videos of some of the world's fastest cars in action. I'm also addicted to the "Spy shots," which is just what you think it is. What's surprising is that the writing is of such a high caliber. It's entertaining and informative. Using the ad supported magazine model, they ask you to sign up for three years, but have a solid privacy policy in place -- and heck, you can always cancel.
