I'm in a similar position, but not exactly. My car is set to go into production. My total cost was $106,820. This included the rear next gen seats, tech package, alacantara, air, etc. Now my same car would be $105,450. I would gain the interior lighting, and nappa leather, but lose the rear next gen seats. For me it was a wash, and so I'm sticking with my original and hoping it gets here quickly.
