When you've found the exact vehicle you want, take the lowest price quote, then call or email the internet manager and make an offer. Even if you received a reasonable price right off the bat, don't be afraid to make a counteroffer for less. It's part of the process, and dealers understand that. Do make sure you stay in the pricing ballpark. Let the internet manager know you've received offers from other dealers and, if needed, refer to a specific quote if there's any reluctance to bring down the price.
There are a number of places to purchase a used auto. Here's a quick rundown: CarMax offers no-haggle pricing and cars that are in good condition, but its prices are a bit higher than you'll find elsewhere. Private-party sellers have lower prices and can be negotiated with more easily, but the burden is on the buyer to get the car inspected. Major dealerships sell certified pre-owned cars that are in excellent condition and backed by factory warranties. This option will appeal to buyers who want to minimize the risks of buying used and are willing to pay extra for it. Independent used-car lots are another alternative but can vary wildly on price and the condition level of their cars.
Cons: While buying new might be the most satisfying way to buy a car, it's also the most expensive. Some cars depreciate faster than others, but no matter what you're buying, your new car is going to experience depreciation the minute you drive it off the lot. That's not to say buying a new car isn't a good value, but it's a financial hit you should keep in mind if you're shopping for a new car. Consider doing a little homework on the depreciation rate of the car you have your eye on before pulling the trigger.
