I don't like 'em because they'd make it look like the side of your car sits higher (you can't always make out the black). Also, it reminds me of those 90's cars with black bottom pieces that people would paint body color to look better and lower to the ground, lol.
I love the M logo as well. In M-B land, it's considered a big poseur tacky no-no to put any AMG badges on a non AMG car. However, with BMW, considering there are "M" logo's all over our M Sports, and BMW offers M Performance parts, would something like an "M" license plate holder be considered poseur or "wannabe"?
