Just bought a MKVI without it, px'd a Scirocco with it.
It's definitely a good bit of kit and does what it says on the tin but I opted without it and don't miss it all all. The standard ride is great on the road, slightly choppy around town on the 18"'s.
For Rolfe with her mum and matey doing track days then yes get it, it works. For me and most others, I wouldn't bother.
