Well I have been fortunate enough to live 30mins away from the ring for the last 7 years and have driven 4 of my cars on it. The last 2 (06 Civic Si and My 1er) were broken in on the way down there. I love what that sticker represents and I will spark up an hour long conversation with anyone bearing that mark. Regardless if they have driven it. It shows that yuou are educated in boy-racer car terms. Usually if people start bragging about cars and such I ask if they know what the ring is and if they say no, I end it there. And yes I've known about the track for a while. I actually never knew it was so close to my home until 4 yrs ago. But anyway, of course the sticker will prompt the question of whether you have braved the green hell, but any good car guy or gal will not stop a conversation just because youve never been there. So if anything just GT4-it-up!! Its extremely realistic!
And yes the sticker is on the 1er.
