The only way to deal with it is to sell a rescue vehicle.
There are several ways in which a junk car can be disposed of – particularly if you happen to know an amateur blacksmith. The alternative that will get the most cash out of it for you, though, is to sell them as a salvage car to a company that separates them and sells the pieces that still operate to individuals who have cars that can be kept operational that way. If that’s what you’re doing, you’re going to get more money out of it than you will by trade, and you’re not going to have to pay for the blacksmith’s removal of anything left over (because not everything in a car can be re-worked in a forge).

Fortunately, to use this, all you have to do is know where you can go and find a salvage car company that will give you the best price for your vehicle. There are a lot of them out there, and the larger a market one has, the greater demand they will have for everything they can do. In order to sell products, this would directly translate into a greater demand on their part for the parts they need. So, they’re going to judge the value of anything you bid higher and be more likely to quote you a decent price for the car you want to sell.
Whatever you want to do, getting rid of your rescue vehicle will still be a much better choice than just leaving it in your yard. It might seem like a fun thing to climb on for kids, but it’s also a natural shelter for molds, bugs, and vermin that can spread diseases and end up damaging people directly at the same time as decreasing your property value by making everything else look pretty ugly. In some way or another, it’s best to dispose of it so that you don’t have to deal with the issues of holding it around.
