Exonian's first reply was perhaps a little harsh
Ok, a little harsh maybe and I apologise. Must’ve been having a bad week.
I’m waging a one man war on wind deflectors
I have learnt a few things from this thread though, interesting as always to see different people’s take on things.
I’ve also been paying closer attention to cars I’ve physically seen with wind deflectors these last couple weeks to see how they’ve been attached. No mk7 Golfs unfortunately (or fortunately depending on your take). A workman was parked around the corner from me all week with a Bora sporting the delightful deflectors so I had a close look. The heavily sloped rear door windows were a very different shape to the Golf ones so not really a useful comparison. I did try though!
