I have had a couple of cars over the years that I bought on PCP with a modest deposit and still been in positive equity at the end of the deal.Anyone buying a car and expecting anywhere near positive equity needs their head examined.
I wasn't with my first EV but do however look like I may be with my Born (as I got a big discount when I bought it)
PCPs for EVs (unless you get a 0% Apr and a big discount deal) are turning into a more expensive form of leasing. The outcome at the end of the deal is the same, people are handing their cars back.
