About the 2020 FORD MUSTANG

The 2020 FORD MUSTANG is a large car with a 2261cc petrol engine. 2,330 of these vehicles were MOT tested in 2026, making it a reasonably common sight on UK roads. Among all cars from 2020, the average MOT pass rate is 92%, and this model falls short of that benchmark.

With an average of 18,792 miles at 6 years old, FORD MUSTANG 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 FORD MUSTANG Fuel Costs

The 2261cc petrol engine offers a reasonable balance between performance and economy. Expect around 30 mpg in mixed driving, which works out to roughly £1,592 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 2020 FORD MUSTANG?

Total estimated annual running cost is £2,042 (£170/month), broken down as £1592 fuel, £195 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 92% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

FORD MUSTANG Reliability Trend

Newer FORD MUSTANGs show better MOT pass rates than older ones, with an average improvement of 4 percentage points.

Buying a Used 2020 FORD MUSTANG

At 6 years old, the FORD MUSTANG 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 2022 model has the highest pass rate at 96%.

Common Issues to Watch For

Based on the 2020 FORD MUSTANG's fuel type, age, and engine size, these are the most likely problem areas to check.

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.
