New, no, not necessarily an EV but any new vehicle is simply not worth the initial depreciation imho, many people seem to lease nowadays and treat their cars like mobile phones, changing them prematurely as a fashion item, or to keep up with the jones! So there’s always a plenty of almost new cars available at a massively reduced price compared to the original retail.
Both our EVs have been bought that way, very low mileage and between a third and half of the original price.
As for commercial motor homes despite the obscene prices the build quality is often so poor I don’t know why anyone buys them new!
Although in my later years I can now afford to do so I just couldn’t
However same argument can apply to new houses! The build quality is often staggeringly poor!
