I don't have splashguards and was thinking of the oem ones at H and A. I did a bit of a search and can't figure out if they're functional or more of a just-for-looks accessory. I can't believe how much winter crap splatters up the sides of my E. I know the guards won't stop it all but will they at least cut down on the amount of sloppage? So, what do you think - are splashguards worth it? Oem? Aftermarket? Thanks.
