With VAG ‘longlife’ servicing the car may only get one service in 3 years, which isn't a very good deal for £900, is it? A PCP leaves you with an amount to pay at the end. If that is less than the trade value of the car at the time you still have a bit of equity to use as the deposit on the next car. Probably only a few hundred pounds, though. If the amount to pay at the end is more than the trade value then you have
nothing, and if you return the car you will have to pay for any damage to it. That's how M.T. of Henley got done last year. Alternatively, if the amount to pay at the end is more than the trade value, but less than you would have to pay retail, you might choose to buy the car and not have a new one.
