I have badges on my car - one's Autobot the other's Decepticon. Just go badge up your car dude. Don't let the fact that some posers might be doing it ruin it for you. We were into Transformers long before it was mainstream; it's not like any of us have decided to quit being Transfans just because TFs has become mainstream now. Think of wearing TF apparel or having TF logos on your vehicle as being akin to people who wear apparel and have stickers of their favourite sports team; they may or may not be a "real fan," like people who sport English Premiere League stuff... they're not always fans, but that's not gonna stop the real fans from wearing their logos/imagery.
