I love my Touareg. From what I gather the 04 Touareg was a nightmare. From 05 and later, things apparently changed. I just know mine is fantastic. Only real problem is the HID headlight auto-level sensor went out. Its $800 to repair a sensor (the lights work fine, they also still auto-level properly, just the limiter sensor is broke) and at 97,000 miles I'm not going to repair it.
The Touareg is one of the few SUVs on the market that actually is heavy on UTILITY. You can load it up with plenty of heavy stuff, you can tow over 7000#, and it is actually capable off road. Most SUVs, especially the mid-size units, are grocery getters for soccer moms.
What I'd like is a LARGER Touareg with a diesel engine.
I've heard rumors...
