I am based in the UK.
I have enquired with a couple of dealers one replied with this pricing schedule:
Service 2 - £330.18
Service 3 - £631.33
Service 4 - £330.18
Service 5 - £487.93
And the other one actually suggested to go to a third party:
To keep the warranty intact, the car just needs to have services at the correct intervals (Every 12,500 miles or yearly)
The service just needs to be done at a VAT registered garage.
I wouldn't go to Kwik-Fit to change a tyre on my bicycle!
I know a couple of hi-tech garages where I live, will enquire with them. Doing some online research I found that EU law requires car manufacturers to release their service schedule manuals so other service providers can do them too. So it is plausible that some garage with proper tech can do this.
I am buying a used car which means I can not get the 3 year service deal for £500+ that is usualy offered to the new car buyers. Oh well will start a piggy bank to collect the pennies.
