I have 2 ideas for you:

I started a pretty successful business when I was younger. At 22 years old I bought a used airplane because I always wanted to fly. Traded an instructor to get my license by giving him hours in my plane. Now the plane is worth about 5 times what I paid for it.

I bought a 2-year-old Ferrari. Sold it 8 years later when somebody offered me way too much money for it. Now I'm halfway looking for a used Ferrari 360 Spider as I think that that may appreciate in the future. Much more fun to drive than a stock. LOL
