VW Vortex is good with a huge How To section. edition38 will be of little use unless you are thinking of lowering your car onto the floor or attaining the latest "scene" fashion. You will also pay scene tax on anything in the classifieds.
If you want decent technical advice, broken down by model then you can't go wrong with clubgti.com. I was a member for years when I owned my Golfs and the people on there are friendly and possess a wealth of knowledge.
