Car makers use dealers to sell new cars. And used car sales also are dominated by dealers and wholesalers that want buyers to come down to the lot, take a test drive, listen to a sales pitch and haggle over price.

Not much has changed about how manufacturers and dealers sell cars—at least until now. The automotive industry is undergoing a transformation, and that re-invention of how new and used cars are sold is driven by ecommerce.

After no change in more than a century, ecommerce is set to transform automotive retailing. The 92-page 2020 Automotive Ecommerce Report analyzes the data and trends driving ecommerce forward and reports on the opportunity ahead for companies of all sizes, and on who wins—and loses—in the race to acquire digital car buyers.

The report also includes a detailed analysis of the overall state of disruption in automotive ecommerce, including which manufacturers, dealers and other sellers are making the move online, who’s not, and what’s driving growth in an ecommerce market that’s already generating nearly $15 billion in annual web sales.
