If you're thinking second hand I'd really highly recommend an oil consumption test done. If new rotate it for a new one before warranty runs out.
With a 1mm,1mm,1.75mm ring package on the vw/audi 1.8t and 2.0t aren't built for longevity. We have a fix at work(it actually kept us open over the real strict lockdowns) so even a second hand one with high oil consumption on the cheap is not a bad idea. I've just built a forged engine for a friends R. The factory gasket kit is poison though at almost 2k trade.
They can also have cam tension issues going by the amount of valve "kissed" pistons I've seen.
BUT don't let any of what I've said as a negative about the car itself. The GTI is my preference of the hot hatch department, it drives a lot lighter and more "flickable" than the R.
