About the 2003 Mitsubishi Colt

The 2003 Mitsubishi Colt is a small family car. Our records list a 1597cc petrol engine, though engines vary between versions. 73 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It sits in the bottom 5% of 2003 models for MOT pass rate.

Total estimated annual running cost is £2,428 (£202/month), broken down as £1,398 fuel, £275 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 62% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

Mitsubishi Colt Reliability Trend

Newer Mitsubishi Colts pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Buying a Used 2003 Mitsubishi Colt

At 23 years old, the Mitsubishi Colt 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 2013 model has the highest pass rate at 83%. Note: with only 73 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.

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 84k 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 62% 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.
