Porsche 718 Cayman — common questions
- How much is it to lease a Porsche 718 Cayman?
- At an MSRP of $74,000, a 36-month lease with 10,000 miles per year, a 0.0027 money factor, and $7,400 down works out to roughly $962 per month, with about $9,562 due at signing. Over the full term that is approximately $43,219. Your actual payment depends on the money factor and residual your dealer and leasing bank offer.
- What is the residual value on a Porsche 718 Cayman lease?
- A typical 36-month, 10,000-mile residual for the Porsche 718 Cayman is around 58% of MSRP, or about $42,920. Residual percentages are set by the leasing bank rather than the dealer and are not negotiable, though they change with term length and mileage allowance.
- How much does a Porsche 718 Cayman depreciate?
- The Porsche 718 Cayman is modeled to retain about 70% of its value after three years and 60% after five, meaning a loss of roughly $22,200 in the first three years. Retention is strong for the price point, and the GT4 and Spyder variants have at times traded above sticker. Running costs are the lowest of any car on this site outside the EVs.
- What does it cost to own a Porsche 718 Cayman per year?
- Including depreciation, insurance, maintenance, fuel, and registration, the Porsche 718 Cayman is estimated at about $11,473 per year over five years at 5,000 miles annually — roughly $956 per month. Depreciation alone accounts for 52% of that.
- How much is insurance on a Porsche 718 Cayman?
- Budget around $2,200 per year for an agreed-value policy on the Porsche 718 Cayman, though quotes vary widely with driving record, garaging location, annual mileage, and the insurer's appetite for the model. Specialty collector policies with mileage limits can cost considerably less.
- Is it better to lease or buy a Porsche 718 Cayman?
- The Porsche 718 Cayman retains about 70% of its value after three years, which is a meaningful loss to absorb personally. Leasing shifts that risk to the bank and is often the cheaper route over a three-year horizon, particularly if the manufacturer is subsidizing the money factor. Compare both with your own numbers before deciding.
