Compareiseasy:In other words the total amount due should not really include the "option to purchase" payment in case they try and include this.
Incorrect.
A PCP agreement is an agreement to buy the car with an option to handback at the final payment point. If you take no action, the finance company will try to take the 'balloon' payment as a Direct Debit one month after your last monthly installment. This is set out in your schedule of payments in the beginning.
The Optional Final Payment (Guaranteed Future Value) is indeed part of the total amount payable.
