About the 2005 Smart Forfour Black Edition

The 2005 Smart Forfour Black Edition is a city car. Our records list a 1124cc petrol engine, though engines vary between versions. 41 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It sits in the bottom 3% of 2005 models for MOT pass rate.

With an average of 102,558 miles recorded at its 2024 MOT tests, Smart Forfour Black Edition owners tend to use this car less than the typical driver.

2005 Smart Forfour Black Edition Fuel Costs

The modest 1124cc 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 2005 Smart Forfour Black Edition?

Total estimated annual running cost is £2,100 (£175/month), broken down as £1,175 fuel, £170 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 61% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

Buying a Used 2005 Smart Forfour Black Edition

At 21 years old, the Smart Forfour Black Edition 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. Note: with only 41 tests in our data, these figures should be treated as indicative rather than definitive.

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

Watch out

With an average of 103k 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.

Higher Than Average Failure Rate

Watch out

With a 61% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.

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.
