Porsche 718 maintenance: the schedule, the costs, the traps
A mid-engine sports car (2-door) with a gas powertrain. Below: the service intervals with real cost ranges, the repairs 718 owners actually report, and the mileage windows worth buying ahead of - whether you are keeping it for yourself or putting it to work.
Service schedule

Known repair windows
What 718 owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new 718 at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $475 | $40 |
| 3 years | 36,000 mi | $1,725 | $48 |
| 5 years | 60,000 mi | $4,400 | $73 |
| 7 years | 84,000 mi | $6,225 | $74 |
| 10 years | 120,000 mi | $8,800 | $73 |
| 15 years | 180,000 mi | $13,200 | $73 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this 718 is known for is Turbocharger wastegate actuator rattle/failure (2.0L/2.5L flat-4) from about 30,000 miles ($1,500-$3,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Chain-driven (no timing belt). Bare '718' = the mid-engine sports-car family; gas 718 production ended Oct 2025 (no 2026 gas car; EV/next-gen delayed). Turbo flat-4 on base/S/GTS-4.0-turbo era; GTS 4.0 and Spyder/GT4 use NA flat-6 (bore scoring largely engineered out via coated bores). Factory 10k/1yr synthetic; many owners shorten to ~5k for turbo cars; severe/track use shortens all intervals.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a gas 718 retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
