What is a 2017 Porsche Boxster S worth today?

About the 2017 Porsche Boxster S

The 718 Boxster S marked Porsche's controversial shift from naturally aspirated flat-sixes to turbocharged four-cylinders, yet delivered impressive performance gains. The 2.5-liter turbo flat-four produces 350 horsepower, 50 more than its predecessor, while maintaining the Boxster's legendary mid-engine balance. Michael Mauer's design evolution kept the classic proportions while adding modern LED lighting and refined aerodynamics. The 982 platform brought improved chassis rigidity and sharper handling dynamics. While purists initially mourned the loss of the flat-six's soundtrack, the S variant's strong torque delivery and 4.4-second 0-60 sprint won over many skeptics. Values have stabilized as collectors recognize this as a significant chapter in Boxster evolution, particularly manual-transmission examples which are becoming increasingly sought-after in today's PDK-dominated market.
