I have ACC and actually use it more than I thought I would. Sport mode is really very firm and I can only stand it for a few miles when I'm by myself and feeling frisky. I sometimes put it in Normal, but 90% of the time - and 100% of the time when I have passengers - I use the Comfort setting. The difference between the 3 settings is not huge, but it is noticeable, especially when you flick from Comfort to Sport. I drove a non-ACC car before ordering mine and that was way too firm for my taste (more or less like the Sport setting ). It's a fairly expensive option, but well worth having, IMO. It was one of the reasons I went for the Golf in the first place, TBH: it's one of the only cars in its class to offer a relatively comfortable ride. That said, the ride of our Renault Espace is incomparably more compliant, so don't expect limousine levels of comfort from the GTI, even with the ACC on Comfort.
As for xenon lights, yes they are nice, but not worth the additional cost, IMO. I have had them on 3 previous cars, 2 of which had the active system for lighting up bends. Hmm, yes, I suppose it is a plus, but to be honest, I think it's a bit of a gimmick. I don't think I ever drove round a badly lit bend quickly enough to have to rely on them. I will probably get slated for this, as pro-xenon members absolutely love them, but personally I don't think they're that important. They do look cool, however
