The argument for buying outright and keeping your EV long term is probably a good one if you're happy accept the depreciation. I'm. sure it would be worth something at end of 10 years though.
For those amongst us with a low boredom threshold and who like having a newer model the prospect of losing a huge amount of your initial investment* is probably not sustainable.
A PCP or lease deal might be a better way of owning one as it allows you to get the newer model at the end of the term.
My mates £100k Taycan Cross tourismo is now 2 and a bit years old and he's been offered late £30k's/£40k for it.🤷🏻♂️
The motor industry needs people to keep buying new cars, holding on to the for years doesn't work for them.
There's so many scare stories out there about EV's, it's relatively new tech in it's current form, I'm sure in a few years things will settle down or there'll be a new way of powering vehicles by then.
*investment* not in terms of a money making proposition......!
