In my opinion, small interior dress up with carbon fiber that is sourced through eBay or overseas isn't necessarily terrible. It doesn't get as much UV exposure as exterior parts so yellowing in the clear isn't as much of an issue along with durability. If the look is right and it's real carbon instead of something hydro dipped or a look a like, I wouldn't worry too much about it. I'll provide a link to the dash kit that I currently have installed on mine. It's been on for a little over 2 years and it still looks just fine.
