Well I thought my point was clear enough to understand, maybe have another go at trying to understand what I wrote
If you could keep the passive aggressive attempt at condescendion to a minimum it would aid the discussion I think. I know you didn't say it's inherently bad but that has been stated in this thread by other posters.
You say yourself you are struggling to comprehend if rolling a pcp is good for a consumer or not after previously saying on Leo's case buying the car outright at the end was the a good idea.
A pcp is just the financing method, trading your car to buy a new one is a standalone decision regardless of how you financed a purchase, I'd argue it's rarely a sensible decision financially speaking but people buy cars for more than financial reasons.
I'll say it again, if you can get 0 percent or an interest rate below prevailing inflation pcp can be a good way of financing a car, it offers protection against depreciation to a point (important with evs at the moment as the market is still volatile)
At the end of 3 or 4 years you can either pay the final payment and keep the car, you can trade it in against a new car (from any brand or dealer) if its trade value is higher than the gmfv, you can sell it privately and repay the final payment and pocket the difference or you can hand it back and walk away if it's value is lower than the gmfv.
Taking the above into account whar concerns your or is unclear?
