The cost of a used Tesla is starting to fall, new data shows.

Axar.az reports that up until fairly recently, it seemed that customers were happy to pay more for a used Tesla than a new one to avoid having to spend months on a waitlist. The buoyant market also proved lucrative for current owners who found they could make a few bucks by selling their Tesla electric vehicle (EV). But that opportunity now looks to be disappearing fast.

Data shared by Reuters on Tuesday suggests that prices for used Teslas are falling at a more rapid rate than vehicles from other automakers.

It shows that the average price for a used Tesla last month was $55,754, down from $67,297 in July, marking a 17% drop. That compares with a 4% fall in the overall used-car market in the same period.
