Just as easily. You can sell a 10 year old Leaf for $3200 locally and advertise it to someone as "no oil change, no gas station" and they would fall in love with it and buy it, and it keeps depreciating further due to range getting lower. People buy cars with emotion and it is more of a toy and dream than a tool these days (see $75000 pick up truck thread).Maybe this dealer can't exploit potential EV buyers as easily as the can exploit ice buyers?
A buyer with outstanding credit , and self discipline is likely the least desired customer a car dealer wants to sell to.
Fundamentally it is all about depreciation and how things change in the EV scene way too fast for anything old to worth anything reasonable. Just like computers in the 90s, they were build like a tank compare to today's standard and they would run for 10-20 years without failure, but people just replace them every 2-3 years as software keeps asking for more processing power and storage due to advancement. EV from 10 years ago may still work with 50% of the range and get you somewhere but compare to new ones that are way more useful, they have to depreciate to the right market price.
