Are you thinking about getting a used car loan? If so, here's something to think about.

A warranty of fitness for a particular purpose applies when you buy a vehicle based on the dealer's advice that it is suitable for a particular use. For example, a dealer who suggests you buy a specific vehicle for hauling a trailer in effect is promising that the vehicle will be suitable for that purpose.

If you have a written warranty that doesn't cover your problems, you still may have coverage through implied warranties. That's because when a dealer sells a vehicle with a written warranty or service contract, implied warranties are included automatically. The dealer can't delete this protection. Any limit on an implied warranty's time must be included on the written warranty.

In states that don't allow "as is" sales, an "Implied Warranties Only" disclosure is printed on the Buyers Guide in place of the "As Is" disclosure. The box beside this disclosure will be checked if the dealer decides to sell the car with no written warranty.

In states that do allow "as is" sales, the "Implied Warranties Only" disclosure should appear on the Buyers Guide if the dealer decides to sell a vehicle with implied warranties and no written warranty.

The best advice is to compare different loan programs to find the one that's best for you. Keep an eye on the fees. Take notes, and compare, compare and compare again. Then you'll make a smart decision.
