Gosh ... myabe it is just me but I'm still taking that in. I'm just thinking, even if it takes them the whole day, say a whole 7 hours to do the service. Thats still £420 labour inc (at £60/hour you mention). So the parts cost around £1200 inc? Maybe I'm looking at this too simplistically.
However, I used to own a BMW 7 series (E38 - still do actually) which I bought when it was fairly new (a couple of years old) and I used get quoted all kinds of full service rates, from £800 all the way to £2k ! Such variance! (Scotland was always cheaper for me, especially Perth). So what I used to do was get the very basic service done which used to be around £300 and get them to mark all the things that needed changing / required work done to it (they do this as part of the service). Then I would buy all the parts that I required from BMW and take it to my mechanic mate to fix. That way I got the stamp I needed, got all the original parts and had all the work done by my mate in front of my eyes!
I wonder whether Audi has a basic charge for servicing? Can't be that high surely!
I hope its not a case of RS6 = expensive car with discerning driver taste = affordability = high service rates = £1.5K .... Just thinking aloud ...
Gosh I'm not looking forward to mine !!!
