There are so many websites and apps to find used or new cars that you never have to walk into a car dealership uninformed. You can check sites like Edmunds for any car's specs, like horsepower and gas mileage. Or check Craigslist to find cars people are selling in your neighborhood.
But you can search and search for good prices, but never know if you're getting a good deal. For instance, a low-cost car could be available on the cheap for a reason. Maybe it has a lot of miles on it.
The No. 2 car-shopping site CarGurus, from a co-founder of TripAdvisor, specifically sets out to find the best deals in your neighborhood. When you search for cars on its app, it ranks results by comparing a car's price to its Instant Market Value, which is its estimated fair price. (See photo next page.) CarGurus uses algorithms to analyze millions of car listings every night.
On the app, you input the make and model of the car you're looking for. Input your location and CarGurus will show your results, starting with the best deals for that car.
