I hadn't seen many cars with fake badges lately (i.e. AMG badges on C250s), but alas, there are many out there.
Spotted Monday night when I was in San Luis Obispo, CA:
BMW 5-Series with a lone ///M badge on the left and a Turbo badge from a Porsche on the right. It had dual exhaust, so it definitely was not a M5, M badge was on the wrong side, and it's most definitely not a Porsche.
