Test drive it and make sure every single feature is the way you want it to be. Examine the car in daylight, never at night. Look under the hood and make sure, for example, that if it's supposed to be a V8 engine, that it really is. Many times, consumers are misled because they are buying a feature, and the car doesn't have that feature. Most people think they are buying something fresh out of a box. Because that pressure to make a sale is on, the salesman will generally tell the consumer anything to get that signature on the dotted line. Once the contract is signed, it's generally yours, so it's necessary to check every single detail on and in the car to make sure it's what you wanted.
UNDERSTAND ALL THE DETAILS OF THE CONTRACT
Because there's such fierce competition for customers, dealers will do everything possible to sell a car right on the spot. They want consumers to sign papers immediately. One problem with this is that the dealer might say things to get the customer to sign without reading the contract.
They could say the customer is only bound to pay a certain interest rate for six months, when it's actually 60 months. Buyers need to understand that, in the contract, they are obligated to pay a specific interest rate for a certain amount of time. A consumer is bound when they sign, so they must read carefully.
Another scam that occurs often is when consumers buy a car and are contacted days or weeks later and told that, due to some unforeseen problem with their credit or with a bank error, they must come back to sign a new contract, always under terms that result in a higher priced car. This scam is called "Spot Delivery with Yo Yo," where the consumer is told to return the car at a later date.
Bring someone with you when you sign, and never rely solely on the dealer to explain the terms of the contract. Always read it.
Never relax when you buy a car. If the situation seems too easy and too relaxed, you may not be paying close enough attention, so go over the details again. It is a binding contract between you and the dealer. Buyers must read the terms and conditions. It is necessary to read what you sign because it tells you what you are obligating yourself to do and it tells you how you may enforce that contract if you need to.
