My service costs (1.6 crdi) will be higher than yours so no point me listing them (I've had 2 services so far, at 12.5k and 25k).
HOWEVER, that figure seems extraordinarily high considering my two so far were £136 then £224.
Aww shoot, I just listed them anyway
ALSO, you have to consider that you'd be committing your ca$h upfront to a dealership that may well not be in existence to fulfil the contract in the future. I know that sounds harsh but that's exactly what happened to my supplying dealership, who incidentally offered me a similar "service deal", but which no longer exists. In fact they went under just a few months after I took delivery.
My opinion is... leave it alone, even though there is breakdown included (how long is the breakdown cover for and what level of recovery will it have?)
