I not too long picked up a CPO 07 IS250, maybe a month ago. What I noticed since I saw it in the dealership was that there were many scratches along the bottom half of the door panel, that part that pulls out so you can put a drink in the cup holder. Looked like the previous owner kicked the door every time they came out the car. The most I've tried is soap and water.

What would be the best thing to get rid of these scratches/scuffs?

 

they arent going to come out, its scratched plastic. If the scratches are just on that one panel you can replace it if it bothers you that much.
