This is found under the help link, 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.

into account millions of data points including make, model, trim, year, mileage, options and
vehicle history.

What's in our Deal Ratings?
To calculate our deal ratings, we compare the asking price of a vehicle to what we estimate
to be its fair market value the CarGurus Instant Market Value, and factor in dealer reputation.
From this calculation, we rate the quality of the deal: Great, Good, Fair, High or Overpriced.
We always show what we believe to be the best deals first based on our algorithm, not how
much a dealer pays us.
