You never wear shorts. Ventilated seats will blow tepid air on your arse AFTER you’ve burnt it 😂
In all honesty, with the mileage I do and pampering my F gets, wear doesn’t concern me. However, as many have said before, good quality Alcantara is hardy.
As for cleaning, leather is excellent for family wagons - I wouldn’t have anything else. As for the F, my kids are only allowed in it after completing a lengthy application form. If and only this gets approved by me, they can sit in the car - but I insist the kids are cling filmed wrapped before entering the vehicle 😀
