Hands down, Car and Driver is the best. Their editorial insight (as well as wit) is unprecedented. Motor Trend is Cheesy. Automobile's okay, but sometimes it is too artsy. Autoweek is terrible. Pay attention to all the errors they end up having to correct in the back pages every week. Also, WAY too much racing coverage. I've never understood why just because you like cars means you like racing (ie. Nascar, F1). About the only racing worth watching is SuperTouring.
