Hi
I've just got a mk7.5 gti last week and getting used to it. Coming from an old bmw z4 it's definitely a different drive for sure,definitely easier to drive which is good for a daily driver.
Looking at all the bits to do on it to make it more personal to me,nothing extreme though.
Dash cam install
Replace some of the interior lights with brighter LEDs
Bigger undertray maybe a good one.
Remove rear wheel spacers (didn't spot then when I bought the car 🤦♂️)
Bought a warning triangle and a tyre inflator (exciting stuff eh).
Not sure about changing the air intake, enough power for me at the moment so might be good for the sound, something to look at long term.
Need to give it a good clean too when it stops raining.
Will try and take photos and post them afterwards
