I like my stick on crap "V6 Kompressor" badge!! Very subtle and looks stock. Most people think it is factory badging. However, I agree that you must be very careful with the stick on badging, it can go wrong very quickly. Too much looks cheezy. I just did it to stir a little conversation and to tie the German origins to the car without explicitly referring to MB or AMG. I really don't like stick-ons, but I did this a bit hypocritically with the knowledge that I could remove them at any time. I like 'em though surprisingly.
