Your interior is probably Dark slat gray and Medium slate gray. No interiors were Sapphire Silver Blue Matallic.

When I touched up my interior I used products from Leather Works. It has stood the test of time as the areas I refinished look like the day i applied the stain. It works really well. Thing is the product is more like a paint than a stain. I also got the tinting toner so I could match the colors as time has faded everything. I think the Medium Slat Grey color is Leather Works # 6559S. I also used their color prep and cleaner.

When you get your headlights good and clean/polished ( auto parts stores have kits) you can buy clear vinyl film ( kit by Expel ) to cover the headlight plastic and then use Mequiar's Plastic X to keep then shinny and new looking. I refinished my headlights 14 years ago and they look new. Both the vinyl and Plastic protects from UV rays
