Buying a car is a major investment; one way that you can lower the cost is to buy a used car. There are actually quite a few good reasons to buy used, the biggest is the massive depreciation that new cars take as soon as they are driven off the lot. The process of buying a used car is pretty simple but t there are some things to watch out for.
The first thing that you have to do when you are buying a used car is to figure out how much you can afford to spend. This should be fairly easy if you are planning to pay cash for your car, a little bit trickier if you are going to be financing. If you 
are paying cash you can just look at how much money you have available. If you are planning to finance the car you will need to determine how much you can afford to pay each month and then work out what this works out to as a purchase price, there are plenty of online calculators to help you do this.
The next step in buying a used car is to decide what kind of car you want. You will want to start with a general idea, do you want a sports car or a family car for example and then narrow it down from there. You are going to want to do research on the cars that you are considering. There are lots of places that you can find out which cars are more reliable and what the approximate value should be. One thing to keep in mind at this point is that some cars have a reputation for being highly desirable used cars. In general you will have to pay extra for these so you may be able to get a better deal by going with one of the many perfectly good cars that doesn’t have the same reputation.
