• Fuel consumption
• Maintenance costs
• Insurance rates
• Past repair record
• Safety record for that make and model

A lot of good information is available through consumer magazines, which track manufacturers' safety records, as well as buying trends. Another valuable source, is the "blue book", which lists approximate values for used cars by make, model, and age.

There is also a Used Car Rule, set down by the Federal Trade Commission, by which all dealers who sell more than five cars in a 12-month period, must abide. Exceptions are banks, dealers who sell to employees, lessors who sell to lessees, or someone recommended by the lessee. It also does not cover private sales of used cars.

The Used Car Rule is set out in The Buyer's Guide, a booklet that the dealer should give you when you are considering the purchase of a used vehicle. It will provide you with such information as

• If the vehicle is sold "as is", or with a warranty. Ask for a copy of the warranty
• How difficult it is to enforce oral promises or agreements. Have the dealer write any proposals in the place provided in your booklet.
• What costs the dealer will be responsible for during the warranty period. The warranty itself is part of the purchase price. Service costs may be extra.
• You have the right to ask for an inspection by an independent mechanic, prior to purchase. If you have asked for the repair record from the previous owner, and suspect it is not accurate, you may also purchase a vehicle history report, from various agencies.
  

There is more to buying a used car, than kicking the tires. Go through your Buyer's Guide carefully, and don't settle for verbal assurances, when you're unclear on any item. Negotiate only when you have all the information you asked for, and don't be rushed by promises of time limited offers, or other "specials" that can lead you to sign the contract before you're ready.
