What it costs to fuel
Across its configurations, the 2017 Cayman costs about $3,200 to $3,650 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $3,362. Over five years that is about $16,812 in fuel alone before maintenance, insurance and depreciation — which is why the running cost, not just the price, decides what a car really costs.
Relative to an average new vehicle, this Cayman configuration spends about $4,500 more on fuel over five years.
For context, the average combined economy of two seaters in this dataset is about 23 MPG. The Cayman sits roughly 1 MPG above that mark at its midpoint, making it more efficient than average for its EPA class.
