What is Instant Market Value?

Back in 2006, there weren't any popular automotive shopping sites that let shoppers see whether the price of a car was above or below market value, and by how much. Let's say you were choosing between two silver 2015 Honda Accord LX sedans. How could you tell which was worth more? The certified pre-owned one with lower miles or the former rental vehicle with no accidents?

That's why CarGurus was the first major shopping site to create and show users the results of an algorithm that accounts for all those differences, as well as broader characteristics like make, model, and location. This algorithm calculates the values of every car that we have sufficient data for, which we call Instant Market Value. We compare each car to similar vehicles listed in the last 5-15 months and run our calculations daily, leaving you with a valuation that's relevant and up to date. And since our site has the most listings of any major shopping site, we're able to get a real sense of what's going on in the market. This means you get a super-accurate and up-to-date car valuation every time.

After calculating a car's Instant Market Value, we compare it to the list price and factor in dealer reviews from users like you, all so we can give each car a deal rating from Great Deal to Overpriced. Unlike some car-shopping sites, we automatically show you the best deals first to make finding the right one simple.
