I understand the passion completely, it's just that I have seen aaaaaalot of guys (including myself on a prior project) put in a lot of $ and time on a restoration (part or full) and then wind up wanting to the sell the car soon after it's completed, resulting in a large loss ($8k+ in my case).
That has left me to conclude that it only really makes financial sense to restore the more collectable/desireable cars.
Having said that, your car is coming along great and I hope you get a lot of enjoyment from it.
