About the 1999 Ford Mustang

The 1999 Ford Mustang is a city car. Our records list a 0cc petrol engine, though engines vary between versions. 101 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 13% of all 1999 models for MOT pass rate.

With an average of 85,621 miles recorded at its 2024 MOT tests, 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.

1999 Ford Mustang Fuel Costs

The modest 0cc petrol engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £1,175 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 1999 Ford Mustang?

Total estimated annual running cost is £1,810 (£151/month), broken down as £1,175 fuel, £230 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 88% pass rate. Keeping on top of servicing will help avoid surprises.

Ford Mustang Reliability Trend

Newer Ford Mustangs pass their MOT more often than older ones, by 4 percentage points on average, which is mostly down to age and wear.

Buying a Used 1999 Ford Mustang

At 27 years old, the Ford Mustang is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2020 model has the highest pass rate at 92%.

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.

Coil Pack Failure

Medium risk

Smaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Medium risk

With an average of 86k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

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.
