took out a 2 year service plan on my 2018 Sport recently.
These Honda tailored plans do seem to vary in cost and what you get for the money.
Year 1 ( 6th year ) standard service + includes brake/clutch fluid change , MOT , Courtesy car , wash and vac., roadside assistance , recall check , health check.
Year 2 , as year 1 , except brake fluid.
This cost me £670.
Also bought a years extended warranty for £380, but I doubt if I'll renew next time.
