How many used cars were sold in the US last year?

I do not have access to real-time information, including the number of used cars sold in the United State in the last year. The provided information is up to the end of 2019. According to the data available to me, approximately 40.2 million used cars were sold in the United State in 2019, with an average purchase price of $23,931.

These figures are based on data collected and analyzed by reputable sources such as the National Automobile Dealers Association (NADA) and J.D. Power. However, it's worth noting that the automotive market is constantly evolving, and these numbers could be significantly different when considering more recent data.

For the most accurate and up-to-date information, I recommend consulting a reliable resource or industry expert who specializes in the latest automotive statistics and trends.
