About the 2020 Porsche 718 Spyder

The 2020 Porsche 718 Spyder is a luxury car. Our records list a 3995cc petrol engine, though engines vary between versions. 319 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It ranks in the top 5% of all 2020 models for MOT pass rate.

With an average of 8,356 miles recorded at its 2024 MOT tests, Porsche 718 Spyder owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2020 Porsche 718 Spyder Fuel Costs

The 3995cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,958 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 2020 Porsche 718 Spyder?

Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 98% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Porsche 718 Spyder Reliability Trend

The Porsche 718 Spyder has maintained consistent MOT pass rates across model years, varying by only 1 percentage point.

Buying a Used 2020 Porsche 718 Spyder

At 6 years old, the Porsche 718 Spyder offers good value with plenty of life remaining. Most manufacturer warranties will have expired, so a pre-purchase inspection is worth the cost. If you're flexible on year, the 2019 model has the highest pass rate at 99%.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Timing Chain / Belt

Watch out

At 6 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.

Oil Consumption

Low risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
