Traded in my M3 2nd Dec at Manchester and they looked around the car and checked that all the cables were present. But my new MYLR had the same anyway so no loss.
I guess they’d expect the standard mats, so if you’ve upgraded you could take them out and put the originals back.
When I traded in my car a few months ago, they didn't even look at it. I left in the new Model Y and the 3 was parked out front, no issues.
I did leave matts and cables (type 2 and universal), as in the terms they send over, it does say to include these. You wouldn't want Tesla chasing you after taking your new car...
