Lol Zafira

Yesterday I saw a Vauxhall Zafira driving down the road. It was blue and a couple of years old. Nothing to write home about I suppose. Just a sensible people carrier. But this one had been fitted with a HUGE exhaust and dump valve. I have no idea why. It makes no sense to me as the Zafira is not the sort of car suited to a huge exhaust or a dump valve. Why do people do things like this? It makes no sense to me! Buy a different car or just leave the one you have alone if your going to embarrass yourself like that.
