Buying A Used Car

Read the contract carefully.
Make sure any verbal promises are included in writing. Before you sign anything, take the car to your own mechanic to have it checked out.
Make sure you understand the Buyers' Guide.
A Buyers' Guide must be displayed in the window of all used cars sold by dealers. It usually states that you are buying the car "as is". That means after you've signed the papers, any repairs are your responsibility. If the dealer promises to make any major repairs or do anything other than what is written on the Buyers' Guide, get those in writing.
Don't buy the first day you look.
Take time to compare prices offered by several dealers. Check the dealer out with the Better Business Bureau before you shop there and find out if they have a record of complaints against them.
Don't just accept dealer financing.
Most of the time you can find better interest rates through your credit bureau or bank. Shop for the best interest rates. Figure the total price of the interest into the price of the car to see just what the actual price will be when it's paid off.
Don't sign anything until...
you get the name and address of the previous owner and contact him or her to find out about the car's repair history as well as if there were any major problems.
