This car has cost me so much. Full synthetic oil changes, premium fuel (I average 17 mpg), and incredibly high maintenance cost. It's a very comfortable car but it's not worth the headaches and repairs. $300 for an O2 sensor, $900 for crank case vent valve, $373 for mass air flow sensor, and now the Cats need replacing....$1600. To top all that, I'm upside down on the loan at the tune of $4k. Don't do it.
This is my second Touareg, first was a gasoline, 2004, had a few problems as it was the first year out, this car is much improved and a rocket ship, faster than the sister Porsche by .6 second, (Cayenne S), no problems so far in 5000 miles.
I love the power and torque, great for hauling my boat, etc., gets 25 mpg if you go the speed limit on the highway.
I wish it would power my phone, etc. When the motor's off, all plugs are off, it's got two batteries for crying out loud. Steering wheel could move up higher, too, for easy entry-exit.
