Federic,
First thanks for sharing some awesome pics!! That A5/S5 is definitely splendid! Personally, I would change the badge to A5 and add 1.8TFSI or 2.0TDI badge just so I could see people's reaction when I approach from behind and fly past them with a mean grumble. HA!! (jsut kidding!)
absolutly stunning, im still a fan of the filthy car look tho, im lazy
