Nope I don't think there is a difference. The grade and quality of the leather is exactly the same. Note that the leather portions of the seat are only where your legs, butt and back touch the seat. The edge and sides of the seats are all leatherette.IIRC, tthere is a difference in the grade of leather between these two models.
The touring has two seat memory positions versus one for the EX-L. That's about it.
