For all of you experienced homebuilders:

Let's say that I were to acquire a GlaStar kit (one that contains all standard parts and components that originally were included in the kits - no missing parts). Let's say that it included no instruments or avionics, and nothing firewall-firewall forward. Just a bare-bones GlaStar kit.

And let's say that I wished to finish that kit as a plain-Jane, basic VFR airplane; no frills, no extras. And with a serviceable (not runout, but not freshly overhauled) Lyc 0-320.

Best guesses as to the dollars required to turn that basic kit into a finished, flying airplane? (Not including the cost of acquiring the kit.)

Thanks in advance for your educated guesswork!
