Hey, I got my limited edition corsa last Tuesday, and well there is a scratch on it and that's going in for repairs hopefully on Tuesday. Also when I put the wiper on, it keeps banging on the windscreen and making funny noises. It does this infrequently, it's only one of the wipers as well. I am not sure if it's a faulty blade, or something is wrong with the mechanism....but the noise it makes is quite worrying! Any help would be lovely, thank you but the rest of the car is perfect!
