My question to you is, what do you want to end up with? If you eventually want an early S, you already have a beautiful car with (in my opinion) a desireable sunroof option. You know the condition of the chassis as you restored it. Are you looking to swap dilemmas--sell this car with beautiful and solid body and get one with an S engine but needing lots of body repair?

I sense you feel you're getting to the point (if not already there) of being upsidedown on this car, especially if your goal was to have an S with proper engine. The car, as you describe it, runs and drives well. Depending on what you really want, I would say to continue with the interior restoration, and start looking for an S core/case from which to start your eventual rebuild. The money you'd get from your car now would not go too far in purchasing a numbers matching S in decent shape.
