I'm on my 3rd PCP as they work really well for my current circumstances
After blowing a huge amount of capital over the last few years buying cars outright (11K on a Saxo VTS - i know, i know lol!, 12K on a MK4 1.8T, 17K on a new Bora and 10K into my first MK5 GTi) i decided to treat cars as a rental proposition from then on...
I set myself an 'enjoyment fund' figure that i'm happy to pay per month for the car i want to drive and sort the deal accordingly on a 3 year PCP, on all the deals i've had i have changed cars before the end of the term no problem and without the huge financial losses people assume will come with PCPs, admittedly you have to be mindful of which type of car you choose but most VAG stuff is a safe bet imo
As a quick ready reckoner a 3 year PCP will work out the same per month as 5 year straight finance on the same car, i like the option to hand back the car if needed and because of the GFV i'll never be in a negative equity situation, i also chose a lower mileage allowance than i do per year to keep the payments low as mileage matters not if you trade it in and the excess mileage charge can work out lower than the extra payment per month should you want to hand back...
It's not for everyone granted, but imo shouldnt be dismissed out of hand
