Has anyone used them before?
They seem pretty well priced
They state that they only supply genuine BMW parts, just at a cheaper price than the dealer- too good to be true?
I got my ZHP knob from them - cheapest I could find including postage to Oz. They were easy to deal with and the genuine article arrived a few weeks later.
Great company, if they've got it in stock then the prices are excellent. If they have to order it in then it may be possible to get it cheaper elsewhere eg Soper BMW.
