If you get the dealer to supply the glue as well (it looks like black toothpaste!) it's stronger than you would
ever believe!!

There are no worries of it
ever coming loose!
Wish I still had it, much better than the standard S spoiler on my R53 Cooper S; it even used to help keep the back window clean, whereas the S spoiler does absolutely naff all!
Treat the eBay spoilers with care, I have reason to believe that the shape isn't quite right and it may leave gaps between the body and the spoiler. The BMW item is a quality part.
Before the dealer orders it in white and charges you to spray it, look in the parts catalogue as they certainly used to be able to order many of the different colours at no extra cost. I even had to point this fact out to my local dealer when they said they would need to charge me to spray it!
If you let me know what roof colour you have, I might be able to give you the part number to quote BMW as I still have the price list for them!
Got to agree with you, I Love MINI, Laura, it's a nice looking spoiler!
Tigger.
