Oxygen Sensor is a common failure on the car. We just replaced ours at 53K miles. I got 180K miles out of the one on a Jetta VR6, so I was surprised to see it go so early.
Motor mounts are another thing to look for. I think IPD has an upgraded one. Ours has been replaced already.
Brakes warp. Not bad, ours continue to go in and out of warpage due to whether I drive it aggressively or my wife drives it like a sane person. We're upgrading ours to slotted rotors to try to help them cool.
