Here's how my 25 looks with about 1500 miles on it, picked up in Feb and there were a couple creases already on the tan section.
I'm not overjoyed with it given how much the seats cost, but I'd say it's well within the realm of normal for leather seats. If it gets significantly worse or starts to peel in any way, I'll take it up as a warranty issue, but the only way to keep the seats perfect is to not sit in them!
