Actually, the passenger seat is in amazingly good condition. The driver’s side shows a lot more wear, especially where your back would slide against the edge of the seatback getting in and out. That was one of the first things I looked at when I was trying to guess the actual mileage. How much wear and tear on the driver’s seat. It indicates a lot of start and stop driving.
The 35 year old Corinthian leather still feels better than the crappy cloth seats in most new cars though.
