This is a good example of why I like to look at the Bring a Trailer site almost every day. It's not that I'm currently in the market for a used car (especially one with a "Buy it Now" price of $250k), it's just that I enjoy browsing the vintage street- and race-car photos and reading some of the amazing stories that go along with them. You never know what you'll find listed there.
Regarding this 1970 Plymouth Road Runner Superbird Clone: You can get some of the technical details about this 800-horsepower monster right here, but if you go to the Barrett-Jackson Auction Company site, you'll also find that this exact same car was sold as part of a charity auction in 2009 for just over $500,000. (Kind of makes that $250k price tag seem a little more appealing now, doesn't it?) Also, Barrett-Jackson has a slightly more complete version of how and why the car was built. As it turns out, there were some heavy-hitters in the sport of auto racing involved in this one.
Anyway, that's just one example. Most of the cars listed on the site are a lot more affordable. And if you do decide to make a habit out of checking the BaT homepage every day (or at least once every week), just be careful ... you might suddenly find yourself with a new project car parked in your garage.
