Is It Better to Buy a Used or New 718 Cayman?

Aside from the introduction of the Cayman GTS (the first of this generation), this Porsche is largely unchanged for 2019. You can spend less and get a virtually identical 2018 model instead.

Read about the new Cayman »

Porsche redesigned the Cayman for the 2017 model year, adding the 718 prefix to its name and replacing the flat-six engines from the previous generation with turbocharged four-cylinders. Other notable additions included the availability of Apple CarPlay and blind spot monitoring. No major changes occurred for 2018, so you could save a lot of money by sticking with a similar 2017 Cayman.

You can save even more money with a model from the previous generation. You’d have to get a model from 2016 or earlier to find a Cayman GT4, as Porsche discontinued that trim when it redesigned the Cayman for 2017.

Which Used Porsche 718 Cayman Trim Is Right for Me?

The fixed-roof, midengine Cayman is available in two main trim levels: base and S. There is also a convertible variant of this Porsche, called the 718 Boxster, which we review separately.

The main difference between the two trims is the engine under the hood, since both trims have essentially the same available features. Some models come equipped with sport seats, 14- or 18-way power-adjustable seats, heated and ventilated seats, dual-zone automatic climate control, Apple CarPlay, a navigation system, and a Bose or Burmester stereo.

  • Porsche 718 Cayman: The base 718 Cayman has a 300-horsepower turbocharged 2.0-liter four-cylinder engine. The standard Porsche Communication Management infotainment system features a 7-inch touch screen, a six-speaker stereo, satellite radio, HD Radio, two USB ports, and Bluetooth. Automatic climate control, partial-leather seats, front and rear parking sensors, and a rearview camera are also standard.
  • Porsche 718 Cayman S: The 718 Cayman S has a 350-horsepower 2.5-liter turbocharged four-cylinder engine. It also gains a few sporty enhancements, such as red brake calipers and other distinctive exterior and interior styling elements.

What Does Porsche's Certified Pre-Owned Warranty Cover?

Porsche offers a certified pre-owned program for vehicles 13 years old or less and with fewer than 124,000 miles. Eligibility is determined by the vehicle’s initial sale date. For its certified pre-owned vehicles, Porsche extends the original new-car warranty to six years or 100,000 miles. If the CPO vehicle is past its original new-car warranty term (four-years/50,000-miles), Porsche will cover the CPO vehicle for two years with unlimited mileage. Each CPO Porsche must pass a 111-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Porsche warranty page carefully.

Porsche’s CPO program is below average for a luxury carmaker, according to our research. Audi, Mercedes-Benz, and Jaguar all have better programs.

2018 Porsche 718 Cayman Versus the Competition

Which Is Better: 2018 Porsche Cayman or 2018 Porsche Boxster?

The 2018 Porsche Boxster is the convertible version of the Cayman. Both are good vehicles, and choosing between them is a matter of preference. These two are similar in many ways, with identical engine options, gas mileage, and interior materials, as well as similar features. The Boxster and the Cayman also have the same predicted reliability rating. On average, the Cayman costs around $5,200 less to buy than the Boxster. On the other hand, the Boxster has lower five-year ownership costs.

Which Is Better: 2018 Porsche Cayman or 2018 Chevrolet Corvette?

The 2018 Chevrolet Corvette ranks neck and neck with the Cayman in our luxury sports car rankings. The Corvette is a two-seater available as a coupe with a removable roof panel or a convertible. The Corvette coupe has a larger trunk than the Cayman, though the Porsche’s total cargo space is similar when you factor in its front trunk. The Chevy has much more powerful engine choices, lower ownership costs, and more standard features, including Android Auto, Apple CarPlay, and a Wi-Fi hot spot. On the other hand, the Cayman has better fuel economy estimates and a slightly higher predicted reliability rating.
