Auto salvage yards sell usable parts and cars at discounted prices. You may consider using these yards to replace a broken part in your car, which can be much cheaper than buying a new one. Trading in salvage parts is essentially recycling, and therefore you'll be helping the environment. You may find many almost functional cars in a junk yard, and some of these may be classic roadsters or newer model cars. Sometimes, all they need are a few replacement parts to get back to running condition. Using this method, you can refurbish and resell a car for a profit.
