Three principal sources of financing -- from cash purchases to loans from a bank or specialty-finance companies -- dominated both used and new purchasers' funding sources. Compared to the last Overdrive survey on this topic in 2015, dramatically improved freight rates and trade-in values, among other conditions, may have resulted in new buyers being a good deal more likely to indicate they'd paid cash for the most recent truck purchase (19%, v. 11% in 2015). Borrowers among new buyers were also more likely to have exercised relationships with a bank rather than to have used a captive or specialty institution, flipping the script from 2015. Similar shifts to more cash purchases were seen among used buyers, compared to 2015.
