BMW in helpfulness shocker!
I have a bit of an aversion to the local beemer dealer. The staff tend to treat you like something you might find on the bottom of your shoe. So imagine my surprise when the parts department turns out to be staffed by fully fledged members of the human race!
Phoned them about replacement brake pipe clips. The chap in the parts department faxed over copies of the parts manifest so I could identify the pieces I wanted. After that, he ordered the parts and quoted the price - I was fully expecting to have a heart attack - but all 5 clips cost £1.90. Result.
