Rent-A-Wreck is a car rental company that is primarily known for renting used cars at discount prices. The company's name is not to be interpreted literally, rather as a tongue-in-cheek humor. Rent-A-Wreck vehicles may have been personally owned, or they could have been owned by another rental car chain company. They are also known for accommodating younger drivers, those using debit cards, pre paid debit cards, and in some locations cash, to whom many other car rental companies will not rent. The average Rent-A-Wreck vehicle is about 3–5 years old on average with 40,000 - 70,000 miles.
The company is known as The Smart Alternative, a trademarked phrase. Another trademarked phrase is 'Don't Let The Name Fool You!', referring to the fact that the vehicles in their rental fleet are not actually wrecks.
