A junk car is an eyesore. An old, rusty vehicle sitting around in your driveway won't add any value to your home's curb appeal. It might even make prospective buyers view your property with lesser value than similar homes without an old car in the yard. Exchanging your old car for cash will allow you to purchase a vehicle in mint condition, making your home's curb appeal more appealing. An updated ride will also get you and your family to destinations faster and safer. In addition, an updated ride will have more safety features than the older model, again adding another plus for you and your family.
