Skip the Mk 4s, they were made in Mexico and the build quality was crap. Also the VR6 was heavy, boring, and hard to modify.
At that mileage on a 2.0 T, you are overdue for the major stuff like coils, injectors, chain, tensioner, and carbon deposit removal, so make sure all that has been done.
I have a bunch of friends and family with various iterations of these motors, and they have really grown on me... they seem like really solid motors if you address the known issues.
