X5 M / M Package paint chipping issue
Hey guys, new today to the forum!

I have a deal in place for a space grey 2011 X5 M and recently came across a thread pertaining to the rear fender / lower rocker / sandblasting / rock chipping after just a few thousand miles.

Couple questions

- is this a real issue, and do mudflaps + 3m solve this?

- are the dealers aware, and would you use BMW 3M or a thicker product is what Mercedes and Porsche use?

- would this dissuade you from buying again?

- can anyone in a snowy climate attest to the paint chip effects being worse?

- any Canadians having problems?

My salesperson said he has not known of this issue.

If this is a real issue, I may switch to Alpine White.

Your thoughts and input much appreciated!!!
