My wife loves our mk6 GTI. She pretty much started driving it and never gave it back. No problems with about 25k miles on it now. She wants to run it into the ground, although I am a bit hesitant keeping it past the powertrain warranty to be honest. Not worried about the engine (TFSI/EA888 in the mk6 is reliable), but the dual-clutch trans will be expensive if anything ever goes wrong with it.
It's also a pretty good drive if you want to change things up and take it some days or autocross/track. Not like an FR-S/BRZ, but the torque and refinement are nice.
Also be prepared for the possibility of more tickets. With the refinement and quiet turbo, the speed can sneak up on you. My wife got one of these driving the car.
