From the website:
"The leather trim
is sure to please. Get a close look and check out the quality details and accent stitching. Overland features an upscale leather treatment
on seats, doors and dashboard and heated second-row seats."
Notice the language? They are careful not to ever say "Leather Seats". They did this in 2005 literature referring to the seats as having "leather inserts". I didn't notice this detail in the brochure until after I noticed the vinyl used in my new seats.
You can actually see in this pic that the side bolsters (right half of the pic) are vinyl. I realize my eyes are more sensitive to this stuff than most, but if you look close you can see.
Maybe Jeep will go all leather for the "saddle" up charge. I'm hoping, but not betting on it.
