Good info but should be pointed out that those prices are individual services.
A service plan covering services for two years can be bought, which has its advantages.
I paid £1,170 for a 24 month plan which covers three services, 5, 6 and 7 year ones, or if you prefer, 50k, 60k and 70k miles, with 60k being 'the big one'.
The main advantage of course, is being able to pay by monthly interest-free installments rather than one big payment.
