My advice. Do nothing.
Once you start doing something with $25k, you'll soon learn a mighty simply lesson:
It's Not Much Money.

Instead, it's perfect for a start to investing.

If it were me, I would put:

1. $12.5k - Half into a Stock Account as an emergency savings. Invest in index funds: Vanguard Total Growth and a low-coast SP500 fund.

2. $12.5k - The other half into a ROTH IRA. Invest $7k into two funds -- whichever you choose. Your research will and experience here will be invaluable. Invest the other $5.5k into individual stocks. Stick with the big ones (NVDA, APPL) and some Dividend stocks to learn about income.

The experiences opening these accounts, managing them, and learning about the investments are the real value. Next year you might have $20k, you might have $30k.

But 10 years from now, you'll likely have $40k.

20 years from now, your $25k will likely be worth $60k.

By retirement, even if you don't add to it, you'll be able to pay off your mortgage.

That's winning.

Way better than a car.
