I have had leather for nearly 20 years for two reasons...
1) I find a heated seat to be immensely efficient at dealing with my back problems, and to get that, you almost always have to specify leather, although less so now.
2) Cleaning and removal of dog hairs.
My Toyota has leather/alcantara, which is the best of both worlds as it removes the slipperiness and reduces the 'cold winter bum' factor.
