Usually the payment for the optional extras goes to the dealer with the Advanced Payment going to Motability (although Motability are aware of the total amount paid including optional extras). I would suggest you speak to your Volvo dealer about the extra for the seat upgrade, chances are you won’t have to pay if it is now standard specification. I had the same thing happen with Apple CarPlay which was an extra and became standard by the time the car was built. When I collected the car the cost had been removed from the invoice.
