The Smart Buy Average Market Price is a proprietary mathematical calculation based on actual recent transactions either in your local area or nationally. It provides a statistically accurate understanding of what other buyers are paying for the vehicle you have selected and as you have configured it. Adjustments to the calculation beyond make, model, and trim are normalized based on detailed, anonymized transaction information. This accounts for the fact that most or all recently-sold vehicles included different option combinations than your specified vehicle configuration. The data underlying the Smart Buy Average Market Price calculation are filtered for extreme outliers and subjected to a weighted averaging process that considers factors such as the recency of transactions and the timing of data lags. In certain instances, the calculated result is adjusted to take account of abrupt changes in the market that may not yet be fully reflected by recent transaction prices. In all cases where the Smart Buy Average Market Price is shown there is sufficient sample size and transaction detail to be statistically reliable.
