Purely from my own experience of driving and working on my friend's 2.8 Passat and my own 745ti, go with the Volvo. It feels better to drive and is way, way, way, way easier to work on.
One of the ultra-suck things about those VWs is that whatever breaks, you'll always have the odd one. VW doesn't just use one type of rear brake caliper, for instance. They use 3. And you'll have the one that is the hardest to service. And each one of them needs a special tool.
Maybe your alternator will go out. Of course, your car will have the hardest to find one and nobody on Vortex will have ever seen a VW alternator quite like yours. You'll discover that your car uses one of 5 alternators VW used for the Passat and of course it's the only type that will actually fit your car. Naturally, you'll have the 15.741mm socket you'll need to remove it because a 16mm will round out the bolt and a 15 won't fit at all. If you fit a standard socket to this godawful bolt the whole car will pee oil all over your loafers until you relent and finally take it to a $1,039/hr specialist who also has never seen this particular alternator before.
Then you'll just put a piece of dynamite in the tail pipe and wonder if you should have gotten something easier to work on and more reliable like a Jaguar or Lancia.
