"Once you know what type of car you want to get, shopping for a vehicle becomes a matter of price discovery, or finding a way to pay the best price," says Jesse Toprak, a vice president of TrueCar.com.
TrueCar.com will show you a bell curve of recent prices at dealers in your area. At Edmunds.com, you can find a particular car's "true market value," a price based on actual sales data from your region. Cars.com has a downloadable application to help you browse cars and prices. If you find a website that offers a car-shopping app and it's free, use it, Fix says.
