Here are a few pictures. My headlight looks like it has sanding marks, can I sand it down to make it look better?

Roof vortex generator has clear coat failure. I’m not sure what brand. Should I paint it to
match the car or buy a better carbon fiber?

Center console hair line crack. Wrap it in carbon fiber, get another one in the same
color or paint it blue?

 

The vortex gen looks like some cheap dipped carbon pattern, I’d paint match it to the rest of the car or definitely buy a new cf one. Depending on what you like more. As for the center console just buy a new one while they’re still available new. It will look the best imo

 

I'd probably just get the generator painted to match but that's personal preference.

The headlights can probably be saved with a sand and clear. You can do the sanding following 1 of many online guides and use some good clear coat or I have personally had great success with the 3m headlight restoration kits. They include everything you need from sandpaper to clear for like $20-40.

As for the center console, that crack is where some custom work was done to mold in that gauge; the crack is right on the outline of the original ash tray. You could get a new/used one but there will be an ash tray where that gauge is so you'll have to move the gauge or redo the custom work. I would probably pull that console out and see what you are working with. I bet that the crack is fixable especially if you plan to wrap or paint it. Keeping it the same color after fixing it will still require it to be painted that color after the fact.
