Depreciation may be the bane of new-car buyers, but it’s also the reason so many shoppers buy used. We scoured our annual Edmunds New Car Buying Guides from years past to see what cars we loved back in the day can now be had for $15,000 or less. For each vehicle, we’ve provided a range of years offering the best selection and value. In certain cases, getting an even older model is a viable option, too.
