Love my 07 Passat 2.0T 6M. European made fwiw. 35K mechanically trouble-free miles so far. One electrical problem: in the first winter, on a very snowy day I was stuck on a highway for hours with the defroster on full blast, when the multifunction display (LCD readout for various info, such trip computer, etc.) started showing corruption. After I could ease off on the defroster, the display recovered. It was fine after that, so I left it be but mentioned it at my 20K service a few weeks later. Described the problem, suggested it was overheated, thought they would just smile and nod since it was working fine at the time. Dealership completed the 20K service, said they'd call when the new MFD was ready to install. It arrived in less than a week and took less than an hour to install. BTW, free wifi at the dealership/service dept.
I'll be back to a 47 mile each way commute in a few weeks and am really happy I have the Passat. Seats are comfy, stereo is fine, fuel economy is adequate (~32 mpg over any 100 hour period I've looked at with the trip computer) and the performance is terrific. The 2.0T FSI (nearly a twin to the TFSI in the Tiguan and other 2008+ VWs) is very responsive and has torque pretty much everywhere between 2000-5500 RPMs. You don't need to wait for high revs for fun like in some other cars. Also, the brakes are really good, take a look at the rotors on other makes and then look at the VWs. Big difference.
Also, I really like the interior. Yes, my <$22K car has some plastic on the dash. The not-leather seats (no sport package, either) are terrific in terms of tactile feel and comfort, although the controls are goofy. But I don't adjust the seats but 3x a year when the wife agrees to a manual transmission driving lesson. I really like the red LED "mood lighting", the indigo/red/black gauges, and the little things like the hidden trays, the umbrella holder with proper drain, the ratcheting elbow rest/center console lid and weirdly, the special place for the owner's manual in the glove compartment which goes to show how much the designers emphasized usability.
The only mods I am considering at this point is a second grocery bag hook for the trunk lid (another feature I've never seen elsewhere) and getting the engine computer flashed with APR's 93 octane program. Going with APR since everyone else is hours away and the difference probably wouldn't be all that much.
I think you get a lot of cool features and great performance for a pretty good price if you don't mind asking for a fair price. Mine had a tag for $26.5K, but I payed $21.5K for it new in Mar. 2007. Sticker price was out of my range, and to me too much for what the car is. But it is a well worth it at the price I paid. I expect that similar deals could be had today with Passats at least. Don't know about the Passat CC.
BTW, I am under the impression that the Passat and the Tiguan have pretty much the same interior space.
I always hear that VWs are unreliable. There is plenty of evidence to support this, but if they are as bad as people say, then how can they possibly still be in business? Service can be expensive, but it pays to shop around. In my area prices for the (same) 40K service ranges from $240 to $600, both before discounts and assorted fees. Also, the 2.0T is supposed to be fed 91 octane (US style, AKI) fuel, although it burns 87 safely but with somewhat degraded pep and fuel economy. For the record I buy 93 as my options are 87, 89, and 93 in NE Ohio.
There are plenty of other reasons why I love this car. Given my commute (rarely dips below 55mph, only 2 traffic lights) in a car that eats the miles and is always responsive, it makes a real difference in how I start my day.
