What is IMV?

The CarGurus Instant Market Value (IMV) is an estimated fair retail price for a vehicle based on a detailed analysis of comparable current and previous car listings in your market.

We compute and update our IMV calculations regularly using a complex algorithm that takes into account millions of data points including make, model, trim, year, mileage, options, and vehicle history.

Our IMV is intended to provide pricing guidance but is not an official appraisal or guarantee.

What's in our Deal Ratings?

To calculate our Deal Ratings, we compare a vehicle's asking price with its estimated fair market value—also known as the CarGurus Instant Market Value—and take the dealer's reputation into account.

Based on this calculation, we assign a deal rating: Great, Good, Fair, High or Overpriced. We always show what we believe are the best deals first, based on our algorithm—not on how much a dealer pays us.

Our Deal Ratings are intended to provide guidance when shopping, but they are not a guarantee of value.
