We found the leather seats softened up over time when we had the Tucson Ultimate. This time rond we wnt for the same car, but in N Line S guise and the seats were immediately more comfortable being alcantara/microfibre however, I don’t think the seats in Hyundai are as comfortable as the MG HS (PHEV) a neighbour has recently had!
I would recommend an extended test drive before making any decisions.
