People often buy a car this time of year. So, do you know about how much it takes to go one mile in a car? Typically, it’s more than 50 cents a mile. You probably think gas has a lot to do with that, but the big money is actually in depreciation. That’s a fancy way of saying your car loses value over time. The first year of ownership, it loses the most value. Then, after several years it levels out. In addition to depreciation, you have maintenance, insurance and repairs. So, Clark wants you to be smart when buying a car. First of all, buy Consumer Reports’ annual car buying guide. It comes out every April and is on news stands now. In it, cars are rated on the quality of car and the type of repair record the car has. Secondly, once you’ve figured out what cars you might want, test drive them. The best thing to do is rent a car for a few days – maybe from Enterprise or Hertz, which have neighborhood offices. A lot of rental cars sit in lots on the weekend and will cost you very little to rent. Once you’ve got it narrowed down, go to carsdirect.com and figure out what you should be paying. Once you’re at the dealership, pay only what the car is worth and no more. If you don’t want to deal with that often unpleasant experience, buy through one of the car-buying programs at a warehouse club or at carsdirect.com. Just make sure you have your financing all ready before you buy. In addition, if you buy from a dealership, the dealer is going to try and sell you an extended warranty. Clark is neutral on car warranties, but you should not need one if the car is reliable. And don't deal with the trade-in until you've negotiated a price on the car.
