What to Look for When Buying a Porsche 718 Cayman Right Now

Finding a Porsche 718 Cayman for sale today requires navigating a complex market of turbocharged four-cylinders, naturally aspirated flat-sixes, and specialized track machines. Whether you are searching for a certified pre-owned (CPO) daily driver or a rare GT4 RS, understanding the nuances of the 982 generation is essential to making a sound investment.

Currently, the market for the 718 Cayman remains resilient because Porsche has confirmed that the next generation will transition to an electric powertrain. This has turned the current gasoline-powered 718 into a potential collector's item, especially for high-trim models. Prices for early 2017–2018 base models typically start in the mid-$40,000 range for high-mileage examples, while well-sorted 2024 GTS 4.0 or GT4 models can easily exceed $120,000.

Decoding the 718 Cayman Model Hierarchy

The 718 Cayman is not a single car but a spectrum of performance. Understanding where each trim sits in terms of power delivery and driving dynamics is the first step in narrowing your search.

The Entry Point: Base and S Models

The majority of 718 Caymans for sale on the used market are the Base and S trims. Introduced for the 2017 model year, these cars moved away from the traditional naturally aspirated six-cylinder engines of the 981 generation in favor of turbocharged four-cylinder units.

The Base 718 Cayman features a 2.0-liter turbocharged flat-four producing 300 horsepower. In our experience, this engine is often underrated. Because the peak torque arrives as low as 1,950 RPM, the Base model feels significantly punchier in city traffic than the older six-cylinder cars. It is an ideal entry point for those who want the mid-engine balance without the six-figure price tag.

The Cayman S steps up to a 2.5-liter engine with Variable Turbine Geometry (VTG)—a technology previously reserved for the 911 Turbo. With 350 horsepower, the S model bridges the gap between a comfortable cruiser and a serious sports car. If your budget allows, the S is generally considered the "sweet spot" for those who prioritize straight-line speed over the acoustic experience of a six-cylinder.

The Enthusiast's Choice: The Cayman T

The 718 Cayman T (Touring) is a rarer find in the classifieds. It uses the base 2.0-liter engine but strips away luxuries to focus on weight reduction and handling. Standard features on the T include the PASM Sport Suspension (which lowers the car by 20mm), a mechanical limited-slip differential, and Porsche Torque Vectoring (PTV). For a driver who values cornering precision over raw horsepower, a used Cayman T is often a better "driver's car" than a standard S.

The Return of the Six: GTS 4.0

In 2020, Porsche responded to enthusiast feedback by replacing the four-cylinder GTS with the GTS 4.0. This model features a detuned version of the 4.0-liter naturally aspirated flat-six found in the GT4. Finding a GTS 4.0 for sale is often difficult because owners tend to hold onto them. It offers the perfect "daily-able" package: the glorious sound of a high-revving six-cylinder combined with a more compliant suspension than the GT-series cars.

The Apex: GT4 and GT4 RS

For those looking at the top of the market, the GT4 and GT4 RS represent the pinnacle of the 718 platform. The GT4 is a track-focused weapon with a bespoke aero kit and suspension components borrowed from the 911 GT3. The GT4 RS takes it a step further, utilizing the actual 911 GT3 engine with air intakes placed right behind the driver's ears. Expect to pay a significant premium over MSRP for the RS, as demand continues to outstrip supply in the secondary market.

The Engine Debate: Four Cylinders vs. Six Cylinders

One cannot discuss buying a 718 Cayman without addressing the "sound" issue. When Porsche launched the 718 with a four-cylinder engine, the purist community was vocal about the loss of the signature flat-six howl.

From a purely objective performance standpoint, the 2.0L and 2.5L turbocharged engines are superior for daily driving. They offer more torque throughout the rev range and better fuel efficiency. However, the subjective experience is different. The four-cylinder has a gravelly, industrial tone that some compare to a Subaru or a vintage 356.

When searching for a 718 Cayman for sale, you must decide if the soundtrack is worth the $20,000 to $40,000 premium required to move up to a six-cylinder GTS 4.0 or GT4. If you plan to use the car as a weekend toy, the six-cylinder is likely the better long-term investment. If you are commuting in the car, the turbocharged four-cylinder's low-end torque makes for a more relaxed experience.

Must-Have Options to Look for in Listings

Porsche’s options list is notoriously long and expensive. When browsing used listings, certain options can significantly affect both the driving experience and the future resale value of the car.

Sport Chrono Package

This is the most critical option for any Porsche. It adds the dashboard clock, but more importantly, it adds the "Sport Plus" driving mode and launch control (on PDK cars). On manual cars, it provides automatic rev-matching. A 718 without Sport Chrono is generally harder to sell and offers a less "complete" Porsche experience.

PASM (Porsche Active Suspension Management)

PASM allows the driver to adjust the stiffness of the dampers. The standard PASM lowers the car by 10mm, while the PASM Sport Suspension (found on the T and GTS) lowers it by 20mm. In our testing on rougher secondary roads, the ability to soften the suspension makes the Cayman a much better grand tourer.

Sport Exhaust System (PSE)

Identifiable by the two round tailpipes in the center (rather than the single rectangular exit on the base model), the PSE allows you to open the exhaust valves for a more aggressive sound. Even on the four-cylinder models, the PSE is highly recommended to extract some character from the engine.

Seating Options

Porsche offers four main seat types:

1. Standard 2-way Sport Seats: Good support, manual fore/aft adjustment.
2. 14-way Power Sport Seats: Focus on comfort and adjustability.
3. 18-way Adaptive Sport Seats Plus: The best for most people, offering aggressive bolsters that are electronically adjustable.
4. Full Bucket Seats (LWBs): Made of carbon fiber and non-adjustable for recline. These are highly sought after in GT4 and GT4 RS models but can be polarizing for daily use.

Pricing Analysis and Market Trends

The 718 Cayman market has stabilized after the post-pandemic surge, but prices remain higher than historical averages.

• 2017–2019 Base Models: Expect to find these between $45,000 and $58,000 depending on mileage and transmission.
• 2017–2019 S Models: Typically range from $55,000 to $70,000.
• 2020–2022 GTS 4.0: These are holding their value incredibly well, often selling for $85,000 to $105,000.
• GT4: Used 718 GT4s are rarely found under $110,000, with low-mileage examples pushing $135,000.

One trend we have observed is the "manual transmission premium." As manual gearboxes become rarer, 718 Caymans equipped with the six-speed manual are often listed for $3,000 to $5,000 more than their PDK counterparts, especially in the enthusiast-focused trims.

Where to Buy: Navigating the Search Platforms

When searching for a 718 Cayman for sale, where you buy is just as important as what you buy.

Porsche Approved Certified Pre-Owned (CPO)

Buying from an official Porsche dealer and opting for a CPO car is the safest route. A CPO 718 undergoes a 111-point inspection and comes with a two-year, unlimited-mileage warranty that kicks in after the new car warranty expires. For first-time Porsche owners, this peace of mind is often worth the $2,000–$4,000 dealer premium.

General Automotive Marketplaces

Sites like Cars.com, TrueCar, and Edmunds offer the widest selection. The benefit here is the ability to compare prices across a national level. However, be wary of "bargain" listings at non-Porsche specialized dealerships, as they may not understand the specific maintenance needs of the mid-engine 718.

Specialty and Enthusiast Sites

For high-end or rare specs (like a Paint-to-Sample GT4), enthusiast forums and auction sites are the gold standard. Sellers on these platforms are usually "car people" who have meticulously maintained their vehicles and kept every service receipt.

The Pre-Purchase Inspection (PPI): A Non-Negotiable Step

Never buy a Porsche 718 Cayman—especially one out of warranty—without a professional Pre-Purchase Inspection. This should be performed by an independent Porsche specialist or a Porsche dealer different from the one selling the car.

Key Items to Check:

1. The DME Report (Overrev Report): This is crucial for manual transmission cars. The DME (Digital Motor Electronics) records every time the engine exceeds its redline. Range 1 and 2 are usually fine, but Range 4, 5, or 6 indicates a significant "money shift" that could have caused engine damage and will definitely void warranties.
2. Turbocharger Health: On Base and S models, the mechanic should check for any wastegate rattle or oil leaks around the turbo housing.
3. Cooling System: Check for leaks in the radiators, which are positioned low in the front bumper and are susceptible to stone damage and debris buildup.
4. Brake Wear: Carbon Ceramic Brakes (PCCB) are fantastic but can cost over $20,000 to replace. If the car has PCCBs, ensure they are measured with a specialized tool (like the Carboteq) rather than just a visual inspection.

Ownership Costs and Maintenance

While the 718 is a reliable platform, it is still a high-performance German sports car. Maintenance is more expensive than a standard sedan.

• Oil Changes: Typically required every 10,000 miles or 1 year, costing between $300 and $500 at a dealer.
• Major Service (40k/80k miles): Includes spark plugs, engine air filters, and potentially a PDK fluid change. This can cost between $1,500 and $2,500.
• Tires: The 718 goes through rear tires quickly, especially if driven spiritedly. A set of high-quality N-spec (Porsche approved) tires will cost $1,200 to $1,800.

Conclusion

The Porsche 718 Cayman is one of the last great mid-engine internal combustion sports cars. Whether you choose the torquey efficiency of the turbocharged four-cylinder or the visceral scream of the 4.0-liter flat-six, you are buying a vehicle with world-class balance and steering feel.

For the best experience, look for a car with the Sport Chrono package and a documented service history. While the allure of a low price on a high-mileage 2017 model is strong, the security of a Certified Pre-Owned vehicle or a car with a clean DME report is usually the smarter financial decision in the long run. As we move toward an electric future, owning a 718 Cayman is not just about the drive today; it’s about holding onto a piece of automotive history.

Summary of Key 718 Cayman Specs

FAQ

Is the 718 Cayman reliable?

Yes, the 718 platform is generally considered very reliable. The engines and transmissions (both manual and PDK) have shown great durability. The most common issues are minor, such as peeling interior trim or debris in the front radiators.

Should I buy a manual or PDK?

This depends on your use case. The PDK is one of the best dual-clutch transmissions in the world—it is faster, more efficient, and better for traffic. However, the 6-speed manual in the 718 is legendary for its shift feel and engagement. Manuals generally hold their resale value better among enthusiasts.

Can a 718 Cayman be a daily driver?

Absolutely. With two trunks (the "frunk" and the rear hatch), the Cayman offers surprising cargo space for a sports car. The ride in "Normal" mode is comfortable enough for long highway trips, and the fuel economy on the four-cylinder models is quite reasonable.

What is the difference between a 981 and a 718?

The 981 (2014–2016) used naturally aspirated six-cylinder engines for all trims. The 718 (2017–present) introduced turbocharged four-cylinders for the Base and S models, improved the suspension, and updated the interior technology (like Apple CarPlay).

How do I check for a "money shift" on a manual Cayman?

Request a DME report from the seller or a Porsche dealer. Look at the "Overspeed" counters. If there are hits in Range 4 or above, the car has been over-revved significantly, which usually occurs during a downshift at too high a speed.
