Set a price and stick to it. After you get the perfect price for the used car you plan to buy, stick with that price when you visit the dealer. It will be the upper limit of your trading tactics.
Carefully inspect the car. Take the time to scrutinize every corner of the vehicle. Keep an eye out for scratches, possible replacement parts, paint jobs, small dents, and other issues. Ask if your car is out of warranty.
Base your asking price on the defects you notice. Issue a payment offer that is below the upper limit you defined earlier. Use the issues you’ve seen as the reason you’re offering a low offer. If your car warranty is ending, that’s another reason for you to lower your payment. If they disagree with your offer, ask them for a better price or compare prices of the same car models from other dealers or sales companies. If the car is in good condition, don’t hesitate to make a low offer.
