One of the main things you need to watch for is your seller. It can be pretty easy to tell when someone is trying to pressure talk you into buying a vehicle if you know what to look for. Listen for provocative language –if it sounds a bit like propaganda, it is. You also want to try and get a full history of the vehicle from the time the owners purchased it. Ask if they can provide paperwork, although not everyone will be able to. If the owners cannot show you a record of the vehicles history, ask them questions about it. Of course, if your seller tries to sidestep any of your questions or you get the impression that they are lying, it is best to refuse to buy the vehicle and leave. Furthermore, remember that when you buy a used car, you do not get a warranty. This means that once ownership of the car has been transferred into your name, if anything goes wrong it comes out of your own pocket.
As long as you remember to be warry and to trust your instincts, the difficulties of purchasing a previously owned vehicle can be side-stepped and you will find yourself with a quality car at a decent price.
