It's simple really, get a written quote then you know exactly where you stand![]()
I do not like having to get everything in writing and arrange for some legal document to confirm that the guy in the shop is not talking utter bollox.
It seems to me franchised dealers just cannot resist trying to rip you off at every opportunity, which is very short sighted as by gaining £55 they have possibly stopped me spending thousands over the next few years.
I really do like my bike, but with every BMW dealer I have had dealings with telling bare faced lies I will be avoiding them as much as possible and I am highly unlikely to buy another one, a bit of honesty and I may have kept up BMW servicing, paid for extended warranty and possibly upgraded to a new(er) bike at a later date or my partner may have considered buying a smaller BMW when passing her test.
The BMW dealers I have dealt with can save their precious paper and not need to put anything in writing as I will certainly go independant for all future servicing on the BMW, even if it means a trip to manchester to Adventure Bike Warehouse, and as someone else pointed out for the NOG's £400 services I can get a weekend away in a top hotel as well as the service for less!
That's where I went wrong, taking someones word! I am so last century 

had they quoted me £300 for the whole job I may well have used them, however they did not. Perhaps this is part of "forming a relationship with your dealer" people bang on about and I have not hit the £20k previous expenditure required to get fair pricing.
