Haha, I thought this was a lame thread at first, but I remember back in the day I was worried about the imola leather in an e46. I had some flaps with buttons on some jeans, I think they were monarch, and would put a towel on the seat when I wore those jeans
Nowadays my jeans are free of buttons on the back and any type of obnoxious branding.
I'm kinda into detailing at the moment, but am less anal about cars for some reason. I do worry about dark jeans on light leather though. Especially when either the car or jeans are new.
