2017 Ford Mustang 2.3L Petrol · LB17 AED

The 2.3-litre EcoBoost Mustang is the most frugal variant in the range, with real-world fuel economy typically in the mid-30s mpg for mixed driving — slightly less than official figures suggest. As a 2017 petrol car with a 2.3-litre engine, road tax falls into a moderate band, though exact VED will depend on list price at original registration. Insurance is a significant consideration: the Mustang sits in a relatively high insurance group for its class due to its performance credentials and 2+2 coupe body style, so obtain quotes before committing.

Routine maintenance costs for the EcoBoost are reasonable by sports car standards, with standard service items comparable to a Ford Focus or Mondeo, though specialist labour will cost more. Budget for higher wear on front tyres and brake pads, and remember that parts availability through Ford main dealers is good but some body and trim items may need to be sourced from specialists. The estimated annual running cost, factoring fuel, tax, insurance, and routine maintenance, is in the region of £1,800-£2,400 depending on mileage driven.

Although this particular Mustang has recorded no MOT failures or advisories, the model-wide failure data highlights three areas that warrant close inspection on any used example. First, examine both headlamps closely for condensation, lens hazing, and correct beam pattern — headlamp defects are the single most common MOT failure reason across the Mustang population. Second, inspect front brake pad thickness and disc condition; while this car passed without comment in May 2025 at 36,580 miles, pads are a consumable that will need replacement based on driving style. Third, confirm the windscreen washer system delivers an adequate jet to the wiper swept area, as washer inadequacy is a recurring failure point across the model.

Beyond MOT-relevant items, the 2.3-litre EcoBoost engine benefits from a visual inspection for oil leaks around the turbo and sump, and the six-speed automatic (if fitted) should be checked for smooth shifts. Check the condition of the 19-inch alloy wheels for kerbing damage, inspect the convertible or coupe roof seals for perishing if applicable, and verify that all electronic systems including the SYNC infotainment and digital dashboard function correctly. A scan for stored fault codes can reveal issues that have not yet triggered warning lights or MOT failures.
