Just follow a few simple rules and you should be all set:
First, make sure you have the registration for the car. This will allow you to save some time when you go to a shop that might be interested in buying your car. Paper work is still essential even if the car is being sold to be junked.
Second, make sure you have proof of what state the car is in. Any person you will be dealing with will need to have an idea of the condition of the car. Yes, you are selling it for scrap but any scrap yard still has some standard to follow when making a purchase. So it is important for you to be able to describe the condition of the car in detail like whether it runs or not or what type of body work history it has. It also would be better if you have a picture available for viewing.
Third, you should make sure what kind of price you have in mind is something fair. You would do well to do proper research and find out what people get for something similar to what you have.
So if you want to have a chance to tell your friends “I was able to junk my car for cash” just follow these three simple rules.
