I just ordered and installed a spoiler on my wagon. Do not do this if you are a beginner!!! This requires drilling 7 holes through the sheet metal and the factory templates are not that great. After starting, I ended up going to a body shop to get help. Though I probably could of done better without the help of the two rocket scientists that were trigger happy with the air drill at the body shop. I can only pray for no leaks!!! It looks good though, this would be something worth paying the dealer to do!!!
