Porsche 718 Boxster GTS 4.0

The reason to choose this Boxster

The Boxster GTS 4.0 introduced in 2020 brings a naturally aspirated four-litre flat-six to Porsche's two-seat roadster. That engine distinguishes it from the earlier 718 GTS, which used a turbocharged 2.5-litre four-cylinder. The suffix matters: a GTS badge alone does not establish which engine is fitted. Confirm the factory specification rather than relying on a photograph of wheels or trim.

Its particular attraction is six-cylinder power without the Spyder's different roof routine and chassis brief. This is a desk-researched ownership guide. We have not driven this model for this article. Published enthusiasm for the engine is context, not our own listening or driving experience, and it does not decide whether the actual seating, ride and controls suit a prospective owner.

Manual at launch does not mean manual only

Porsche's January 2020 announcement described a six-speed manual. Later that year Porsche announced seven-speed PDK availability for the six-cylinder 718 range. Do not use the original launch release to claim every GTS 4.0 is manual. Obtain the build record, original market and installed transmission before comparing cars or quoting the performance of one configuration as if it applied to both.

The choice is practical as well as emotional. Try low-speed manoeuvres, hill starts and ordinary journeys in the configuration being considered. A manual requires a clutch and selection assessment; PDK needs checks of cold and warm operation, reverse and fault history. Neither a manual lever nor a dual-clutch unit guarantees lower ownership costs or a particular resale outcome.

A powered roof is part of the purchase case

Unlike the contemporary 718 Spyder's more involved roof arrangement, this Boxster retains powered hood operation. Demonstrate a complete cycle following the handbook, checking movement, latching and window coordination. The mechanism should be assessed on its actual condition, not simply declared sound because it reaches the closed position during a brief viewing.

Inspect fabric, glass, seals and the drainage system, and look for moisture in the cabin and storage areas. A musty interior warrants investigation, including any electrical consequences of water entry. Ask about previous leaks and obtain the repair trail. A dry carpet on a sunny day does not establish that a recurring problem has been resolved or that hidden areas remained dry.

Engine history and current campaigns

Review dated servicing, fluids, ignition maintenance and any cooling-system work. Porsche-specific diagnostics can contribute useful information, but ask the inspecting technician what a report can and cannot establish. An engine that starts cleanly is not thereby certified internally healthy. Investigate warnings, coolant loss, poor running and unusual noise rather than treating every symptom as characteristic of a performance engine.

Published buying advice discusses a connecting-rod recall affecting a limited group of six-cylinder 718s. That does not mean every GTS 4.0 was affected or that an unaffected car needs the same work. Check the actual VIN for applicable campaigns and documented completion with Porsche. A model-wide forum post or registration date is not a substitute for the vehicle-specific record.

Chassis and brake specification

Porsche's launch material describes GTS-specific equipment and larger front brakes than the contemporary S. PCCB ceramic brakes were an option, not a universal fitment. Identify what this car actually has and obtain a condition assessment appropriate to that system. A general replacement-disc price from another Boxster is not a useful estimate for an unidentified brake package.

Assess adaptive damping, tyre age and suitability, wheel damage, alignment and suspension condition. A lower sports-car setup needs to fit the roads and entrances where it will be used. Inspect the underside for contact damage and examine repairs to the front bumper or other low components. Fresh tyres should not prevent investigation of the alignment or suspension that wore the previous set.

Seats, cabin and luggage

Try the installed seats rather than valuing them from an option list. A supportive seat can still be uncomfortable for a particular driver, and specialised alternatives change access and adjustment. Check pedal reach and visibility with the roof both raised and lowered. The car should fit the people who will actually drive it, including anyone sharing the purchase.

Test climate control, heated equipment where fitted, infotainment, phone connection, locks and both keys. The period cabin does not have every function available in a newer Porsche, so confirm what is installed rather than assuming a missing feature is broken. Try real luggage in the front and rear storage areas, respecting their limits and the potential effect of heat on carried items.

Maintenance money and use history

Request a written estimate separating the next service, worn consumables and unresolved faults. Dates matter alongside mileage on a lightly used roadster. Review storage and recommissioning, including tyres, fluids and low-voltage power care. A recent battery replacement and a clean exterior do not establish that every time-related requirement has been completed.

This guide has no current workshop-quotation survey and does not invent an annual service tariff. Add insurance, tax, storage and transport to the actual maintenance proposal. If a warranty is advertised, obtain its written scope and the accepted repair route. Manufacturer, approved-used and third-party arrangements are not interchangeable promises, especially for an import or modified example.

Alternatives and a decision rule

A Boxster S offers a different turbocharged engine proposition; an earlier six-cylinder Boxster introduces another generation's inspection questions. The 718 Spyder may suit someone specifically wanting its chassis and roof arrangement, while the Cayman GTS 4.0 offers fixed-roof packaging. Compare those differences before assuming the more specialised or more expensive car is the right one.

The GTS 4.0 works as a shortlist choice when the six-cylinder engine and powered roof are both part of the intended use. Compare documented condition, gearbox and equipment rather than relying on claims that the last desirable engine configuration must appreciate. Asking prices are not completed transactions, and the evidence here establishes no current value range or guaranteed return.

How this review was compiled

Porsche's launch and later PDK announcements establish the specification changes; published buying advice informs the inspection questions. No test drive, invoice survey or measured reliability study was undertaken. The sources are further reading, not certification of a car. Commission a suitable independent inspection and resolve vehicle-specific campaign and warranty questions before purchase.
