Buying or selling a car can be a stressful experience. The buyer wants to pay as little as possible while the seller wants get as much money as they can. Naturally, both buyer and seller will have different ideas about the car under consideration. It is important for the buyer to already have in mind what they want in a car and then look for those qualities.

News You Can Use

  • The first step to buying a car is to decide what you want. Will you need a two-door or four-door vehicle? A young single person may want a sports car whereas a married couple with children could possibly go for a van. Do you want a stick shift or an automatic? How about a radio or other type of entertainment device? All these factors enter in to your decision as to what to look for. These choices define the basic physical type of vehicle you desire.
  • Now that you have narrowed down you selection, you can start looking at the “how much” types of questions. How old a car are you willing to take? Some people want a brand-new model; other will be happy to take a car that is a few years old. You decide you want a red car – how red? Really bright or a little more subdued? Does this vehicle need to be in excellent condition or can you afford to do some work on the car?

    Some "old" cars are very expensive, mostly because they are rare and are considered classics [Figure2]


  • Your final criterion will be the price. Perhaps you can bargain well and find someone who really wants to sell their car. Then you will (maybe) get a good deal. If the price seems too high, you then have to decide how much you want that particular car. Do the qualities that the car possesses warrant paying the price that is being asked?
