They will dry out & crack over time so it is important to treat them once in a while. I do the leather seats in my wife's MINI twice a year. Only takes a bit of time.
Agreed, they need something.
They need to be taken care of - like anything else, and they need to be prevented from drying.
Just, research what you use, what type of leather it's aimed at - and if it's the right one for he car.
