When assessing used car values for Chinese electric cars and hybrid cars, this 2019 BYD Song DM is priced at $6,971 (¥48,800), retaining approximately 24.8% of its original $28,129 (¥196,900) MSRP—aligning with the 6-year depreciation curve for Chinese-brand plug-in hybrids. Industry data shows its 3-year resale value is around 42.3% of MSRP, with faster initial depreciation than luxury PHEVs but stable value retention after 3-5 years. For those looking to buy used cars, its current market value is enhanced by low mileage, accident-free status, and popular features like remote vehicle control and built-in dashcam, making it worth buying for drivers seeking affordable hybrid options.
