You must have just been unlucky as my drives have been 2013 MK 7 GTD > 2016 MK 7 R 2019 > MK 7.5 GTI TCR and am running a 2019 MK 7.5 R now and none of those cars had any issues or additional work aside from regular servicing.
All these were DSG and I was originally very reluctant to move from Manual but within a week there was no going back, its amazing technology.
The MK 7.5 was the perfect evolution, a really balanced mix of buttons and new tech, with upgraded media system and driver display and something still prefer over the new models which are cabin bare and screen driven.
Yeah I think I probabily was.
I do like the Edition 40 but I think I will get a TCR when I can afford it.
Really hard to find a really clean, reasonable mileage ED40 and you not getting the MK 7.5 lifts, and having had a TCR as company car that handed back at 3 years, and watched their prices, the decent ones are premium, which is reason we personally went for a 2019 Golf R as wife car replacement over a GTI TCR, the GTI TCR would have cost us £3500 more like for like in age and mileage, has less power and no AWD.
Loved the GTI TCR but its mainly for its special edition status and TCR trim. The sub £25000 ones are higher mileage, pushing the 80,0000 miles, whereas the sub 50,0000 miles are in the £26000 > £28000 still.
If really want a GTI, the sweet spot would be a GTI Performance, it will drive no differently from the GTI TCR in real world, but you will save quite a few thousand ££ over the TCR for same year (2019) and mileage
