I presume you purchased on a PCP to get the servicing deal
I bought mine privately and financed a portion by bank loan with a very low APR. The interest charges on the PCP were stupid money compared to the interest on the bank loan so I will still be quids in paying for servicing as I go.
The crafty way around the problem I have since realised is to take the PCP route to get the manufacturer incentives and free servicing deals then pay it off straight away using your bank loan
Win. Win !! You still get the financial golden carrots but side step the high interest by paying off with a bank loan
