It's a TDI
I'm just over 36k on my 2012 Jetta TDI. I have to say that other than some sketchy OEM tires I'm really happy with the purchase and overall usability of the vehicle. Because it's a manual TDI I get an exhilarating driving experience and pull over 42MPG while I"m doing it. It took me some time to adjust to searching out diesel fuel but that's now in the past. I know some dyed-in-the-wool VW owners have bitched about cheap interior pieces in the MK6 but I haven't really had an issue there - perhaps they've just grown spoiled over the years?
There are a couple of things I'd change if I could. The first is a better set of tires off the showroom floor. These break traction easily from a standstill and are poor in wet weather - some of this due to the torque produced by the engine. I find the interior bluetooth mic to be inferior and everyone I call notices I sound like I'm in a wind tunnel. There's not much in the way of mods for such a thing, based on my research.
Otherwise this car provides an excellent driving experience for a sedan, and can be called a poor man's BWI, though I actually think overall it's a better value.
