If the latest data from CNW Research is any indication, it appears dealers are already realizing benefits in their used-vehicle operations from the upswing in supply from off-lease volume and corporate returns.

In an analysis released Tuesday, the firm found that May used-vehicle sales increased across every age group in the one- to five-year-old category.

Specifically, here’s a breakdown of the increases each of these age groups saw in May, as provided by CNW:

One-year-old: Up 3.5 percent
Two-year-old: Up 9.6 percent
Three-year-old: Up 7.9 percent
Four-year-old: Up 7.0 percent
Five-year-old: Up 2.5 percent

The lease-return situation could get even better for dealers, as AutoTrader.com’s Trade-In Marketplace has lease return volume on an upward trend this year through 2016.

Additionally, in what may give dealers some idea of which models are coming out of leases these days, Trade-In Marketplace provided a data set from Polk that illustrates the lease mix by brand and vehicle of model-year 2010 leases, which can be found below:
