Banzai @Banzai Pipeline - Might not need to spend money on sheep skins (or any other seat cover). I normally have my full tonneau on the car with the front (zippered panels) tucked behind the seats. When leave the car, I pull the tonneau panels over to cover the front seats. This keeps the seats from getting too hot. If I have something in the front seats to keep out of sight, then I use the tonneau snaps to enclose the passenger area.
I noticed that you have your top folded away in the back seat. To minimize doing damage to the rear windows of the convertible top, I have posted a process on how to stow your convertible top. Its in 'Resources', or you could just click on this link (click on highlighted word 'link'). Hope you find this info helpful!
