OK. A new car after two years is very unlikely to need a new CV boot so the service will pick that up. If it doesn't then after 3 years it will have an MoT, and every year after that, the boot will be at least an advisory if starting to deteriorate, usually a fail. Good bit of upselling on your part though. 🙂 (It's also what I did for a while. Although i'm now retired, I'm not yet gaga.)
