I had my low 4,160 miles 57 plate Jazz serviced by Brayley Honda (Grays, Essex) for its 2nd year service. Due to the absurdly low mileage, they offered and completed the 2nd year 25k Reduced Service for £80 while I waited.
Looking on the service scheduule checklist, they ticked every box except for the pollen filter which they advised previously they were not going to replace given the car's low mileage.
They stamped the service log book and wrote in 'Reduced minus Pollen filter'.
I dropped my car off late in the morning with them and requested they didn't valet the car, and this shaved the waiting time to 1.5 hours from 2 hours. Grays town centre and Morrisons supermarket are within short walking distance to help pass the time.
I could be mistaken, but my understanding of the definition of a 'Reduced service' is the fact that the spark plugs and air filter were not changed - these are normally changed at 25k miles.
JCB Honda (Ashford, Kent, formerly Drake & Fletcher) quoted £195 for a Reduced service.
It's a shame Honda never offered the £500 for 5 years servicing on the original Jazz, but at least some dealers are prepared to cater for uber low mileage users like myself.
