The leather has become worn and was not looked after by its previous owner on the drivers side i want to know how to restore it.
There is a crack on the plastic where someone must have hit it in the back seat.
The final thing is the door handles have become scuffed and i could leave a mark by scraping my nail down it.

If any of you have had similar problems and know how to restore them let me know
