what documents should i get when buying a used car?
what is the first thing you do when buying a used car?
a used car can be a larger investment than a new vehicle, so knowing about the vehicle before you buy is important. you should research for blue book values of vehicles or visit k&n's website to find out how many people are interested in your make and model.
also, you will need to know if there are any recalls on your make and model (this information is available by searching the manufacturer). if there is no recall then go ahead with purchasing it; but if you run across one that includes airbags then consider running away quick! happy researching!
