Indeed, most people focus on the monthly amount. Dealers even ask you how much you can afford to pay each month then fiddle with deposits, GMV and other factors to get the monthly premium right for you. Look at the adverts on TV saying you can have this car for the magic £299 per month!
My point is more around the fact that PCP is the most expensive way to buy a car overall. It might look good due to a low monthly payment. But in the end it will cost you a lot more than cash or an alternative form of finance. You've also got to factor in, not just your current car, but how you will afford your next car after and so on. For many people their first PCP is the most attractive as they have a decent deposit or paid-for car to trade in. It's the subsequent ones that screw you even more because people 'forget' they should really be saving up a decent deposit for the next car (or saving up to buy it cash at end of contract).
It''s not much different to the catalogues we used to get in the 80's. Everything in the catalogue (even if it's a £20 toy) came with a monthly equivalent price. You could buy anything for a monthly price instead of outright. Obviously it cost you a lot more in the end. And with 80's interest rates, it probably cost you a heck of a lot more. That £20 toy probably ended up costing £40! Today's car finance schemes are little different. If you cannot afford to buy the car outright, you can pay for it monthly and therefore pay a lot more for it in the end.
I'm not saying that's bad, because a large proportion of the population are willing to pay that extra price. This thread was started by a gentleman looking at different ways of financing the car. So I'm trying to point out some facts. If you can avoid a PCP, please do so if you want to keep your TCO to a minimum.
