It's terrible value. If you rented a car from Enterprise, and they asked you to pay to service it, or fit new tyres or brakes, you'd do your absolute nut at them, yet that's exactly what PCP does. How on Earth is that good value?
It also allows people to over extend themselves financially into vehicles they could otherwise never afford to own, and in this case they still don't own them - now with mass unemployment looming and so much of the car industry leveraged against unsustainable credit practices, the industry is about to do its own knees and also damage the economy while they're at it. It doubtless seemed like a great jolly when the sun was shining, but now it isn't the entire economy gets to suffer for the greed of the industry and buyers alike. Thanks. Not.
