Used cars are sold through dealerships, rental car companies, used car superstores and even on the internet. When considering your options, think about your driving habits, your needs and your budget. Ask friends, relatives and co-workers for recommendations before you start shopping for a car.

When purchasing from a dealer, consider the dealer's reputation when advertising claims are made about "no-haggle prices," "factory certified" used cars, or better warranties. Before you purchase from a dealer, ask about the dealer's return policy. Get it in writing and read it carefully. Dealers are not required by law to give used car buyers a three-day right to cancel.

The right to return the car in a few days for a refund exists only if the dealer grants this privilege to buyers.

Dealers are required to post a Buyer's Guide in every used car they offer for sale. The Buyer's Guide does not have to be posted on motorcycles, most recreational vehicles or by anyone who sells less than six cars a year.

The Buyer's Guide is an important tool and should tell you:

• whether the vehicle is being sold "as is" or with a warranty
• what percentage of the repair costs a dealer will pay under the warranty
• get all promises in writing because spoken promises are difficult to enforce
• keep the Buyer's Guide for reference after the sale
• what to look for regarding the major mechanical and electrical systems on the car

When you buy a used car from a dealer, get the original Buyer's Guide that was posted in the vehicle, or a copy. The Guide must reflect any negotiated changes in warranty coverage. It also becomes part of the sales contract and overrides any contrary provisions. For example, if the Buyer's Guide says the car comes with a warranty and the contract says the car is sold "as is," the dealer must give you the warranty described in the Guide.
