You are being offered sound advice here especially around Relax. My advice is negotiate! If you are willing to pay, as I did, three services ahead there is scope for reduction. Furthermore, as I mentioned previously pay for it with a credit card thus you are covered for any eventuality and if you get a 0% credit card it can be spread over a couple of years. Amex had a good cashback offer but check first if the dealer accepts Amex.
