100% sell the car.
You don't have time for this car, nor will you in the future.
Don't burden your parents with your hoarder bull****.

Plan A: Sell it. Move on.
You have 2-3 weeks to find a buyer.
That is plenty of time if you don't get in your own way.

Plan B: Let it rot in the garage for another 30 years.
After you die, your children will drag it out of the ground and sell it to some guy for scrap.
Internet sees pics and says, "What a shame. Another hoarder destroys what was once a decent car"

FOMO is the worst reason to keep a car. And what FOMO?
Either way, odds are, you're never gonna be driving it anymore.
Once the car becomes a trophy paperweight, it's time to sell.

Get a little scale model and put it on your desk, it will accomplish the same thing.
You can even wax the scale model.

Most people need a reason to own a car.
That reason is often actually driving the car.

Would you ever buy a computer that you never turned on?
Would you ever buy a guitar that you never played?
Would you ever buy a car that you never drove?

Justified.

Why would you regret it? You barely even drove it.
What exactly will you regret? Having a giant paperweight in your garage?
I can promise you your only regret after selling will be not selling it sooner.

You don't keep a car because of potential value in 10-20 years.
Consider opportunity cost of money.
A car that sits for 10 years will just rot away.
Either start driving it or sell it.
Invest the money in SPY.
Buy another one later in life, if you want.
These cars will crash in resale value as Boomers start to die off.
He can always buy it back at half of today's cost in the future.
(See Model T, 1957 Chevy, etc)

Most people here will tell you that your SC will be worth $100,000 in 20 years.
Maybe even a few million dollars.

My opinion is not a popular one here, but do the math.

You can get a nice condition Model T for $5k these days.
How hot is the market for '32 Ford or '57 Chevy? These were $100k cars at one point.
60s Muscle cars prices have been on the decline for a decade now.

These are toys that rarely get driven.
Guess what gets sold off when people downsize or get laid off ?
Guess what people hold off on buying when they get laid off ?

Your 911 just doubled in value in 5 years.
It's a great time to sell when an asset doubles at the tail end of a long bull.
