$20k is too much.
Don't get me wrong, its a nice car. But its not #'s matching, it has an old paint job that isn't the original color and will need work to be "perfect", and it has a handful of minor interior issues. The 416 sounds awesome, and I know a lot of money went into it. But it's a 5 year old rebuild on a non-original engine- that's how a buyer will look at it. A rebuilt engine that's been run and was built by someone other than the buyer, or someone he knows, is worth half of what it cost to build.
The problem is your car falls in between what people are looking for. Its not a fully restored and "needs nothing" car. But its also not original. Its a really, really nice driver. If I were in the market its the kind of car I like to buy, because you CAN drive it and you CAN work on it because its not some 100% original, numbers matching, 1 of whatever car.
But the problem with that is the cars that bring the big money are 100% original, numbers matching 1 of whatever cars. Or going with the current market, a fully rebuilt/overbuilt pro-touring or resto-mod car. And really, even if you look at restored #'s cars etc, $20-$25k is the top of the market for an A-body unless you've got something REALLY rare with some backstory.
$20k will buy a lot of fully rebuilt A-bodies. Some of them really nice, some of them only looking that way. Heck $20k will even buy you some pretty decent E-bodies. But that puts your car below that mark. Realistically, I think that your ballpark is probably closer to $16k in the current market. And even at that price I don't think it would sell fast. Trust me, I feel your pain. If I had to sell any of my cars right now, I'd lose money. And even if I finished them, I'd lose money. They'd sell for more, but only because I spent a lot more.
