Relative depreciation, many times, has to do more with perception than reality. Hyundai has been making solid cars for quite a long time now, but it doesnt change the fact that, in the US anyway, people associate them with "budget".
The kia stinger was a great package in the sporty sedan category, out "BMW ing" BMW in most of the categories that (supposedly) "drivers" wanted. Kia poached people from BMW to lead the development of that car, and it looked great, and drove great by all accounts. Kia tried to sell it for the same price as BMW 3 series, and buyers simply were not having it.
A LOT of people are going to buy a toyota or honday, "because its a toyota / honda". Its the same reason a lot of people are buying Tesla EVs even though many dont necessarily agree with how the company does things. Perception is EVs = "Tesla" and then "Everyone else" even though there are some nice EVs coming out now.
Perception isnt reality, but its one reason other EVs have had issues moving volume (and lack of desire from their delaerships).
