Has anyone fitted a better horn to the ROC? Perhaps a louder one from another VAG vehicle is better? I find the weak sound a trifle embarrasing for the R.

Any suggestions?

Having owned my new Polo for just two weeks, I spent a couple of hours washing and waxing it. Afterwards I discovered the rows of dents down either side of the roof where I had leaned on it while working. I was pretty upset that I had just done that to a brand new car. I've never had it happen...
