Never buy a used car if you're instinct is telling you not to purchase it. Don't buy the car if you're hesitant and having second thoughts about the automobile. Remember that it's better to buy a used car that you're comfortable with. Also, it would serve you well to be critical not only ob the car per se, but also to what the perky sales agent is telling you. It's good to ask questions regarding the history of the car and it's owner. Another golden rule in buying used cars is to disregard the car that needs repairs. You'll end up spending more even if you buy the car in a cheaper price; frequent repairs would cost a lot than the price of a brand new car. Don't ever consider buying a flooded car because it's only good at first. But as time passes, the car will no longer work very well. If you want to save up on car purchases, be wise and alert in buying used cars!
