Thank you people. We very much like so many aspects of the Jazz but choosing between servicing possibilities is not so straightforward. For 'ad hoc' servicing over 4 years/50,000 miles the Honda dealer quotes £1193! Honda Happiness Fixed Price Servicing Plan at £500 'down' for 4 years/50,000 miles is not cheap (considering what services really consist of) but is not bad/good value compared to other servicing possibilities. NB: A complicating factor for us is that we may sell the car before 2 services are done and though the Servicing Plan attaches to the car and so could enhance its resale value, we can't be confident of getting the full value of the Plan reflected in the price. After all, it's not a 'negotiable' option.
For us, a very interesting possibility according to the Service Book and the Honda UK website is the Honda Happiness Budget Servicing Plan. The website example shows a 3-year/37,500 miles Plan for a Civic i-VTEC of initial payment of £41.38 followed by monthly direct debit payments of £9.55 = £385.18
For our Jazz, based on projected mileage of 10,000 per year the equivalent 3-year Plan quoted by our Honda dealer is £41.32 initial payment followed by 27 (as we've had the car a number of months) monthly payments of £14.99 = £446.05 total. The payments can be flexed up (or down) according to actual mileage and will be refunded if we were to sell the car or if were to be an insurance write off - or so we are told.
We are keen to keep a 'Honda' service history as we might (regretfully) sell the car while it is still 'young'.
Any observations anyone? Meanwhile, I hope this information helps others.
