My brother had a 7.5 manual, which was so competent at everything, it was bordering on dull.
I have been considering replacing selling my A6 and getting into a 7.5 GTI Performance Pack and having it mapped.
On the subject of the daily van, which is a bit late now yours has sold, I don't think I would daily one if I didn't have to.
I'd love to have the luxury of using a camper for that sole purpose, but for the few times per year, I don't think it's justifiable. For me, the best and worst things about the T6 are that it is a van. I love the practicality of it, I like being able to utilise the load area (even in a SWB Kombi) for stuff I would have to drop the seats in a car, but I still think the car is more comfortable, (mostly) better equipped and cheaper to buy and run. If it wasn't for being able to fit three kids in car seats on the back seat, I probably wouldn't have gone for one.
