Interior lay out of the CTS was one of the big things that pushed me away as was material(suede in particular) selection. The CTS feels smaller than it really is and I think it is because of how they did the interior. Would imagine they will repeat many of the same mistakes on the STS. For those that care about headliners if you cross shop the Caddy cars then look up at that, looks like the same headliner you'd find in a truck but I personally never look at or touch my headliners so do not actually care how they are.
