I have a black interior on my 2005 LS 430

 

might be cheaper to reupholster the seat instead of replacing the whole seat itself.

 

I would purchase a new bottom cushion and have a professional sand and paint the leather. Then they clear coat it. I don't know why some people say re-dye the leather. They paint it. It will look very good when finished.

 

if your car is not a UL I have one I can sell you.
