ferrari daytona spyder
this car originally sold for about 20,000 dollars in the late 60's early 70's. Resale now for one in mint conditions is upwards of 800,000. Pretty incredible. When my dad was about 10 years old he was trying to convince his mom, my grandma, to purchase one, saying it would be a good investment. Kinda wish she listened now. One of the highest appreciation rates of any car.
