A 2013 Mercedes-Benz C63 AMG coupe in good condition has a fair private sale price of approximately $49,000 dollars as of March 2015, according to Kelley Blue Book. However, Mercedes-Benz has produced AMG models over many years, and these models have widely varying resale values.
AMG vehicles are engineered by the Mercedes-AMG group, a high-performance engineering team similar to BMW's M Sport division or Ford's Special Vehicle Team. Although it was originally a separate company, AMG was folded into Mercedes in 2005. Many older AMG vehicles were exclusive to European markets, so they have substantial rarity and resale value in the United States.
