Sorry for the short reply to your question......
but any day of the week, month or year, the Golf wins!
My main reason for purchasing a Stilo over a Golf was the insurance grouping. If I didn't have the points, I would of stuck to my Audi, but prior to that I always wanted a Golf.
After driving my brothers Golf, I see that its pretty similar to the Audi A3 in drive, but the Audi wins anyday in terms of features and looks.
The only positive point on the Stilo (correct me if I'm wrong, as I've only just bought a Stilo) is that the parts seem to be significantly cheaper than say a VW or Audi. And maybe perhaps the "unique" looks you get, although I got much nicer looks when driving my Audi than in the Stilo, lol.
Also, I was able to sell my Audi for the same price that I bought it for a year later and driving quite a significant amount, with the full cost of the year only being between £300-450 on my personal extra's (xenons, roof mount screen & dvd player, mp3 headunit with SD & USB & also parking sensors) but excluding a service at a cost of £200, I don't think I will get anywhere near this sort of return on the Stilo come a year, but maybe the carputer, xenons, parking sensors and a few other extra's I have planned for the Stilo will help boost the value when it comes time to sell.
Well thats my 2 pence on the matter. Hope you have a great buy whatever you end up buying, or have already bought.
