Not a problem for me so far for the 7 months I've had it. Although I choose the parking spots very carefully such as next to expensive cars or kerb/pillar if possible. I drive the car everyday and everywhere so it is usually parked in public car parks. All I can do is just try my best to lower the chances of somebody else's car scratching it.
However, it never has been a head turner or drawn unwanted attention. I've only had "wanted" attention... :)
