CARS.COM — It’s been a year marked by declining gas prices — the national average for a gallon of regular unleaded is $2.01, according to AAA, which is 54 cents less than it was a year ago — and green cars are bearing the brunt of it; three of the top 10 used cars with the biggest decreases in value this year have alternative-fuel powertrains.
The Toyota Prius Plug-in’s value dropped the most of any used car, falling 25.6 percent ($6,224). The Prius Plug-in is based on the previous-generation Prius hybrid and has a larger battery pack that provides up to 11 miles of all-electric driving range before reverting to regular hybrid operation. The Prius Plug-in didn’t make the top 10 in the middle of this year, but its decline in value accelerated during the second half of 2015.
The all-electric Nissan Leaf was a close second; its average listing price fell 25.2 percent ($4,250). Leaf values, however, have stabilized in recent months; they’re down just 3.5 percent ($464) since the end of June.
Luxury cars saw values slide, too, dropping around 20 percent for the BMW 5 Series, Audi A8, Mercedes-Benz SL-Class, BMW 3 Series and Audi A6. The $18,498 drop in the SL-Class’ average price was nearly as much as we spent for our long-term 2015 Honda Fit. Overall, late-model used-car prices are down 3.1 percent ($717) for the year, settling at $22,192.
