Problem with that idea is you'll find what folks are asking. It's much harder to find what they actually sold for.
I found one place asking over $9 for one with 150K+ miles. They'll never get that much. Also found a rough, but not rusty one asking $3K.
You also have to keep in mind that yours isn't totally stock. Which to a collector is a minus.
Is it just my monitor or is that not the stock red?
Plus the interior could get pricey to fix if a buyer can even find the correct parts. Especially if there is a problem with the seats or gauges. Good 1st gen dashes are hard to come by.
Covid 19 has also put a dent in the collector/performance car market. Folks aren't sure what'll happen next and are a bit hesitant to buy expensive toys right now. I was thinking of selling my Corvette, but think I'll hold on to it for a couple more years since the used Corvette prices have plummeted. On the other hand it's a great time to buy one if you're financially secure. If there is such a thing these days.
