Cash for Clunkers

Dan Lyke: This evening we're going to look at a truck that was advertised on Craigslist, a 1991 Ford F-250 that's got a claimed 36k miles on it. The story is that the guy's grandfather bought the car, drove it for a few years and 28k miles, it's been sitting in a garage for 8 years, and then they put another 9k miles in the past 3 years. They want $3.5k, the '91 F250 has a number of recalls on it that probably weren't fixed in that time when it wasn't being driven, so there could be some pros and cons. And back-of-the-envelope says this truck would cost about $.15/mile in gas versus a new 1/2 ton truck at $.10/mile. So I figure that since we're going to be up in Cotati this afternoon we may as well look at it, but I'm not sure it's the right vehicle for me.
[Edit: Didn't get the truck.]
However...
Apparently there's a attempt by Congress to implement a "cash for clunkers" program that'd give you $3,500 if you have a vehicle that gets less than 18MPG (the article says "car or light duty truck" and you trade it in for something that gets at least 4MPG more, $4,500 for something that gets 10MPG more. The official EPA fuel economy web site doesn't give me a "search for cars with less than 18MPG that'd qualify" feature, but I'm kind of wondering if there isn't the opportunity for some Craigslist speculation here...
