I certainly think it is worth doing and even better if you do it right! The plan buys you 3 services for a monthly payment of £35. Your first service with be an A-service followed by a B then another A. It is far better to pay separately for your first A-service in 12 months time as it is nothing more than an oil & filter change and a visual check. Then you immediately sign up for the plan. That way you will get a B, A and a B service. The B-service is far more extensive requiring the removal of the wheels and obviously costs more than an A if you buy it in isolation. Doing it this way gets you to the end of the warranty period for the least money. Beyond this point you will find an independent garage will be far cheaper for annual servicing.
