Personally, I hate the very idea. It's the kind of thing a boy racer would do to his Corsa. Like a fake dump valve or those bits of plastic you glue to your brake calipers to make them look bigger. Cheap, tasteless and tacky. For a major manufacturer to do it is pathetic and certainly lowers my estimation of them.
I think it's the very antithesis of what VW should stand for. Their reputation was built on solidity, reliability and straightforward, honest engineering. Cheap tricks should be left in the Halfords bargain bins.
