Agree with the above comments....I personally prefer to do my own servicing as I then know its been done properly.
I find this a lot, in other walks of life too. If you want a job doing properly then do it yourself (most of the time anyway)
I got my P3 service fluids from Horsham (H-Dev)
If its something I cant handle I'll pass it to my trusted Indy, but no way would I go near a main dealer
