OP GLWS!
The value of anything is worth whatever the buyer is willing to pay.
That being said, now is a bad time to get into unnecessary debt due to rise in rates and the impending recession. People are starting to feel the effects of the rate increases and starting to roll back on spending and only focusing on necessities.
Unless you have a cash buyer, there's really not a big audience for sports cars at the moment.

"This is one of the worst times to buy a car in decades."
The good news for you as a seller is that car supply is still somewhat limited and dealerships are always looking replenish their inventory. If you are in a position where you absolutely need to sell:
1. I would return the car back to OEM. Aftermarket parts do NOT add value, and if anything, can decrease your car's value. The average buyer is not interested in FI and care more so about reliability than performance.
2. Visit a few dealerships and go for the highest bidder.
3. Sell the aftermarket parts on forums in the marketplace.
