The Nissan Leaf is the honest cautionary tale of used EVs. It has no active battery cooling, so its pack ages faster than liquid-cooled cars of the same age and mileage, especially if it's been rapid-charged a lot or lived somewhere warm.
That doesn't make a used Leaf a bad buy. It makes state of health the number that matters. Our model estimates a Leaf's remaining capacity from its age and mileage using a degradation profile calibrated for air-cooled packs, and shows the resulting real range.
Open the Leaf pages and set the age and odometer to the car you're looking at. Before buying any used EV, a battery health check is worth it, that's what the battery-check link on each car page is for.
