Currently checking a lot of offerings for ~1year old X3s.
Biggest difference between two cars which made it to a final check for me is:
Black/Dark Graphite with ventilated seats
Dune Grey without ventilated seats.
As I tried to check thorughly before posting, a lot of people say ventilated seats are a must for „leather“.
Cant compare 1:1 - driving a 3 series with Alcantara/Leather on the sides. Did not feel the need but havent had full „leather“ seats before.
Side Note: Car is in the driveway at home, living in Germany with milder summer (~2months of 80+ degrees).
Curious to get your 2cents
