After my 2016 Jazz had used up its five services on the original service plan, I was persuaded to take out a new two year plan.
This cost £511.60 and included one "Honda 12" service and one "Honda 12 plus". They seem to be the same except the "Honda 12" includes CVT oil and "Honda 12 plus" doesn't (??).
I assumed when purchasing this that it would include all the required service items for the mileage/age.
Silly me.
Seems I need to have aux belt, fuel filter and sparking plugs changed. These are not included in the service plan and and were not mentioned when I booked car in for service. They were all raised on a phone call after they had collected the car.
So "service plan" basically equals "oil changes" (plus some small items).
PS seems the "Honda 12 Plus" has some other items included justifying the "plus".
As it happens I had the plugs changed a few months ago for misfiring, so that wasn't done. But aux belt and fuel filter came to nearly £300.
