I have a 2009 Tiguan. Great car!
Parts aren't cheap locally but, honestly if you order parts from the US it is significantly cheaper than from Best Auto. Only real complaint is the dealer and the headliner drooping. Typical Euro problem.
I had a 2008 Forester and I can tell you it cost me a packet of money with repairs and extremely unreliable. Replaced it for an Audi Q5 2.0T as I'm sold on VAG now.
What I will tell you is avoid the diesel variant. Major problems.
How much are you getting one for?
