For those complaining that their past cars with leather did not wrinkle, are you sure it was actually leather? Yes the dealer made have told you it was and you may have beleived him, but from talking with a friend of mine who grew up in the automotive upholestry bussiness, his dad's being doing it since the 70's and he's worked in the shop off and on all of his life, even some high end cars do not actually use leather.
For the Genney, the center of the seats are leather, but the side bolsters are not. Quick and easy way he showed me to tell the difference. Use your finger to push in on the material, if it wrinkles and shows lines, it's leather, if it dosen't, it's not. Try it on the center of your seat and then the side, you'll see the difference.
But with that said, he was impressed that the Genney has leather in the back seats as he said most high end cars do not, including BMW and Benz.
And I've had my Genney for almost a year and my seats have wrinkles as well. I'm going to start using the Lexol as mentioned. Up to this point, I haven't used anything. And since it is leather, yes it needs to be conditioned. You do it to your leather jackets, shoes, etc, so why would leather seats in a car be any different?
