These self-realizations you came to are sound, financial logic. It's quite opposite usually from "motor-logic".
It also can be used as an underpinning of an axiom that I've always adhered to and that's the further you get away from stock, the more limited your serious buying audience. As a roller, your car will be its closest to stock it'll every get again, opening up your options as well as the buyer's. Which now, you'd have to figure out what to do with all the extra go-parts you removed. Sell, use? WTF? A new set of problems nobody should envy.
Selling a car is never easy, and it's tougher if it's a car you really like. Worse if you have to part one to sell it. Putting a value on it that's both reasonable and equitable is a major headache even if you've sold 40 cars in a month. You say that $45K Canadian probably won't be realized or small chance of it happening. But sell the roller for 8 or 9 K and you'll still would need to make up another 35K or so to sell it all for what you say it should cost on paper. That's a tall order for "used" parts.
As a suggestion, start with option #1. This way you have no labor involved, and nothing else really to do to the car. See if there's any fish willing to take the bait. You may be pleasantly surprised. Be willing to negotiate a little, as labor (excuse me, as y'all would say "labour" 🙂 ) would be saved taking the car apart. And labor time is of some value to you. Or should be.
If that doesn't work, if you find someone remotely interested but balking at the price, you could ask them about option #2. They'd still get a driveable car, and you could still make a few bucks. BUT- it's risky. It's an odd arrangement so the chance it worked would be low, I'm afraid.
I say risky because it's just easier to go from option #1 to option #3 and save having to put stuff back together all the way.
Free advice. Worth nothing if you don't use any of it. First-world problems is all.
