To be frank with you, most of these used units of EVs are the manufacturers own used units, preregisterd units (to meet targets), test drive units, company staff use units being sold by their own authorized dealers. Outside car dealers like us rarely can get thedr EVs traded in because customers usually cannot bear / cope with the on paper losses. For Chinese cars and EVs, most of the loan amounts are higher than the trade in value so many customers have to top up to sell their cars and hence very hard to deal.
