Hi there, I have had my Scala from new in 2020 (as a PCH car) and did a deal at the end of the term to buy it. In line with the contract it has always been serviced at official dealers and has always been on Variable servicing. Last week I took it in for the rear brakes and pads to be replaced. The service department co-ordinator told me about the All-In plan, as I'm due a 40k service in about 60 days time, which would be included if I took All-In out now. She said it would mean me coming off Variable servicing though. I cover around 10k miles a year. Is it worth doing this? The All-In lasts 2 years and covers 2 services, MOTs, breakdown, etc (along with other things) but I think that if I stayed on Variable I would only need 1 service in the same time frame? Seems expensive and unnecessary? Any advice greatly appreciated, thanks in advance.
