Based on VW's reliability history, I'd choose the Sube but thats just me. I agree that V-Dub should be a notch higher than the Honyota's but why do they make side impact airbags or stability control an option? You would think with all the marketing they do about their vehicle's safety that they would make that standard on all of their vehicles! I think it's a huge an oversight when vehicles like the Legacy wagon or Outback have those as standard and offer more space for about the same price.
Those are rear side airbags, not side curtains. So you could have a total of 8 airbags. But the rear side airbags tend to interfere with outboard child seats so they are an option for a good reason imo. And $450 for stability control is really no big deal. The Legacy wagon is imho significantly more expensive (not in the US mind you, but thats another story), and I somehow doubt that it is bigger inside. Legacy rear seat space is quite an embarrassment.
In conclusion:
-VW does give you 6 airbags standard, optional 8.
-VW gives you a dirt cheap ESP program. Until 2008 this was not even available on the Legacy, outside of the spec B IIRC. It certainly wasn't available with the base 2.5 engine.
-The Legacy has limited interior space, particularly in the back seats.
-The Legacy starts at $3.5k higher than the Jetta wagon. Not chump change in this category.
