Five out of the 10 best-selling used vehicles from 2013 to 2015 were electrified in one way or another.

At least, that’s according to numbers from iSeeCars. In this case, “best-selling” doesn’t mean the vehicles that sold the most, but rather it’s those that spent the least amount of time on dealers’ lots.

Of the used vehicles from the 2013 to 2015 model years listed on the site in the first half of 2016, the national average for time on the lot was 42.4 days, while the average for pure EVs, hybrids, and plug-in hybrids was 29.2.

The three best-selling electrified vehicles were the Tesla Model S, Nissan Leaf, and Toyota Prius Plug-in Hybrid.

The lower cost of a used vehicle compared to a new one, as well as other factors that might suppress the prices of used EVs, mean that deal-conscious buyers have a chance to snap up an electrified vehicle on the used market, thus giving sales a boost.

That may especially be true in the case of the Model S, which isn’t cheap in new-car form. With some miles on the clock and depreciation factored in, the car becomes more affordable to many, which could explain why Model S sedans are averaging 26.1 days on the lot.

The Leaf, which is often a good deal on the used market, is averaging 24.3 days on the lot while the Prius Plug-in is turning in just under 20 days, at 19.7.
