Love putting those American 'hot rods' to shame at their own game!
If I ever get a X5M, I think the first thing I would do is de-badge it. Or maybe just leave the X5 emblem on it!
I always laugh when people get a 328i and slap on a M3 emblem or get a 535i and slap on a M5 emblem on it. I've always wanted to do the opposite! BLOW past them at the light and leave them wondering what the heck that was...
Or just for kicks, stick on a X5 3.0 emblem on the side. They won't even mess with ANY X5 after that shock...
