Some people seem to get a new car every year or so. What happens to all the ones they've gotten rid of after just a year? People buy them and sometimes get great deals.
As you read earlier, a large part of a car's depreciation happens as soon as you drive it off the lot. So the main advantage of buying used is that you're buying after this huge drop in price. That makes a used car less of a long-term investment.
Shopping for a used car can be much harder than shopping for a new one. They're like snowflakes. Each one is unique. That makes comparison shopping more of an art than a science. And dealers have a little bit of an advantage since you can't just leave and buy the exact same car at another dealership.
There are three main sources of used cars:
Used Car Dealer
Dealers often offer you a warranty on a used car - which is comforting when a previous owner may have used it to haul chickens down an uneven gravel road every day for the past three years. But you probably won't get as good a price as you will if you buy from the Average Joe/Jane.
Average Joe/Jane
A little negotiation can really drop the price to something that's fair to both of you. But you won't get a warranty. And to look at five cars, you're most likely going to have to visit five different people.
Public Auctions
You can get some incredible deals at public auctions. There is no dealer to haggle with and only other potential buyers will increase the price. The downside to these auctions is that you usually can't test drive the car and it is extremely rare to get a warranty on an auctioned car.
Get the VHR (Vehicle History Report) using the Vehicle Identification Number. It will cost about $10-$15, but this report will let you know if the car has been in any major accidents that may have weakened the frame.
When it comes time for the test drive, be relentless and thorough. Ask the seller about any strange noise the car makes. Anything. It might just be an odd quirk. But it could be a telltale sign of a much larger problem. Use everything in the car. Press every button. Open every window. Open and close every door. Once you are sure there is nothing wrong with the car, get a professional mechanic to do the same. Subtract any small thing wrong with the car from the price you are willing to pay for the vehicle. Realistically, you'll end up paying that money back to get it fixed.
