Speaking of used cars, you also have to realize that there is a time and a place where buying a used car would be the worst idea in the world.
More often than not, that occurs when you absolutely need a vehicle right that second. You may not be in the best position to buy a car then. Of course, that does not really help, does it? If you need a car, you need a car, period.
However, you are in a vulnerable place at a time like that, and you may wind up buying a car that does not run so great simply because you are in need. When that happens, you are most likely going to have to take advantage of the Lemon Law pretty quickly.
Try to take as much time as you can to really be able to test drive a used vehicle and make sure it does not have any problems that are going to pop up and bite you as soon as you drive off the lot.
