What's old, rusty, and probably completely incapable of moving under its own power? That old clunker of a car sitting in your driveway! If you're watching an old vehicle waste away before your eyes, then it's time to take action and turn that trash into cash. It might seem like a huge hassle to offload an old piece of junk that barely runs (or doesn't run at all!), but it's a much easier process than you might expect.
