Wow I thought the M-sport kit was pretty sweet versus the non-version. It would probably be almost as cheap to just buy an E70 stock. The M-Sport package on the SAV model is already $2500 more than the premium version.

It would only make sense that you could get a premium version cheaper than an M-Sport.

I guess to answer your question though, that I would imagine it would be pretty pricy to remove and replace.
