The minute you drive your brand-new car off the dealer lot, it starts to depreciate, or lose value. The rate at which it depreciates depends on a number of factors, and eventually determines how much the car will be worth when it comes time to sell or trade it in for something else in a couple of years.

For used car buyers, cars with high depreciation rates make for great secondhand buys. Since the cars haven't held their value as well, they're often priced below similar competitors.
