Key takeaways

What the data shows

This 2021 base Cayman uses Porsche's 2.0-liter turbocharged flat-four and is approaching the 60,000-mile maintenance window. The most consequential documented concerns are cooling-system leaks, especially the water pump and thermostat, plus clutch and dual-mass flywheel wear on manually shifted cars. These are not automatic failures, but repair costs can be substantial when symptoms are ignored.

Budget roughly $1,000–2,000 for the scheduled 60,000-mile service and check carefully for coolant residue and clutch slip. Ask for records showing the scheduled maintenance and cooling-system work. The $35,054 asking price is below the estimated $43,000 private-party midpoint.
