Lots of places will take old cars, you must have the title though. If you don't have titles to the cars, you must apply for them. If the cars are not in your name, you must locate the owners and go about title transfer from that angle. If they are abandonded, your state will have certain rules/laws that must be followed to have the cars removed from the property. Now, don't expect anyone to give you top dollar for these cars, if anything, sometimes people have to pay someone to take old rusty bucket cars, but they can be gotten rid of.
