I am not going to say the basic interior is better or worst than full leather, but I do not find my leather interior hard to care for. I clean/condition the leather every few months and it still looks like new. It's not hard to maintain at all, and looks great. Plus, leather is far more resilient than plastic. If I was ordering a new Porsche I would opt for the leather interior but wouldn't pay for leather wrapped air vents like the previous owner.
