I bought my X5 from BMW Toronto ... a corporate store ... and they totally tried to load me up with the non-BMW stuff. Boomerangs, paint sealants, third party tinting, you name it... Infact, when I declined everything they still gave me a folder full of non-BMW add on brochures to take home and they gave me a follow up call asking me if I was sure that I didn't want any of the extra stuff.

The business office pushes hard because of the obscene profit on the stuff.
