Re: N/A and SRT Seat differences
I have both and the seats support, warm, and recline/move identically. The difference is the covering. No idea about plugs but cannot imagine they would be different. You may want to check around a couple upholstery or auto shops for someone who could recover them in real leather. I'm not convinced the limited seats are 100% leather all around.
I was dumbfounded to discover my A6 leather seats were only real leather where your butt/back go; the bolsters on the sides were fake leather.
