It all boils down to people wanting something they can't afford - otherwise, why would they commit to a monthly payment thatincludes interest?Would you buy a car outright and offer the dealer an extra 6% (minimum) for the hell of it? Bearing in mind that you couldn't earn anywhere near 6% on the funds in savings in the current market? No, no sane person would do this.
But if you have to sell it yourself, how can you be sure of the price you'll get, especially if a new model is announced, for example?
There are now pretty strict terms about the condition of a car upon return, so they can't shaft you with massive bills if you've looked after the car (and it isn't usually in their interest if you are a prospective repeat customer).
I could return a PCP/lease car in a condition much worse than I'd tolerate for a car I was keeping - e.g. they often can't charge you for dents smaller than a golfball size. If I was selling, I'd be thinking about sorting any little chips etc so the car was hopefully more aesthetically pleasing than the next one viewed.
Also, do you think people shouldn't get a mortgage if they can't afford to pay cash for their house? I mean, many people could live at their parents' house until 40yo and then buy a bedsit outright.
Say what you want, but I've been PCPing cars for years and my salary and savings both continue to increase, whilst any unfortunate life changing incident is covered by insurance. I can absolutely afford the car I lease, whatever you say - it's around 1/16th of my monthly salary. 🤷♀️
