If you're a Twitter user, you may have noticed that carmakers are starting to tweet big-time. And it's not just regurgitated marketing propaganda either.

The @Ford account just tweeted the following, which intrigued us:

@Ford: In 1953, Ford produced its 40-millionth U.S.-built vehicle. We're still going strong! What is your all-time favorite Ford vehicle? #TWIF

So we actually know what our favorite Ford is (and our favorite green Ford, too--can you tell what it is from the photos?), but we want to hear from you.

Tweet your response to our Twitter account at @GreenCarReports. While you're at it, toss in the hashtag #FavFord. We'll round up the results and write about 'em.
