Online doesn't mean 100% honest. People often rely too much on the information in media such as television and the Internet. Just because something is written in a newspaper or mentioned on the radio doesn't mean it's 100% true. The Internet isn't an exception. Promises can be fabricated, as can proof of those promises. The same predators that run shady used car lots can get onto the InternetShady car dealers use the Internet too. The snake oil smiles and slicked back hair can't be seen during a remote negotiation. Programs such as Photoshop allow dings and dents to be taken out of car images. ?As is? is still the rule on the net, but people ignore common sense. Diligence is always wise even though every online car seller isn't a crook.
Always have a used car inspected by a good mechanic. That means driving the car to a garage. Get a mechanic to take a look for you if you won't see the car before the deal is complete. There are plenty of independent garages that will perform vehicle inspections. Don't let the seller tell you where to have it checked. Get a look from someone not involved in the sale. The purchase price and money for repairs can be saved with a small inspection fee.
Don't haggle monthly payments, negotiate price. If the dealer is pushing payment amounts - ?I can get you in this car for $x a month ? demand to know the purchase price. Avoid the dealer's financing because it's often a way to jack up the price. Pay cash or find your own loan. And when you pay cash, demand a discount.
It is possible to buy cheap used cars. There is a lot of help for buyers. But it's true for used cars just as it is for anything, if a deal looks too good to be true it is.
