About the 2003 DAIHATSU COPEN

The 2003 DAIHATSU COPEN is a city car with a 659cc petrol engine. 149 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2003, the average MOT pass rate is 72%, and this model beats that benchmark.

With an average of 63,167 miles at 23 years old, DAIHATSU COPEN 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.

2003 DAIHATSU COPEN Fuel Costs

The modest 659cc 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 £955 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 2003 DAIHATSU COPEN?

Buying a Used 2003 DAIHATSU COPEN

At 23 years old, the DAIHATSU COPEN 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 2009 model has the highest pass rate at 86%.

Common Issues to Watch For

Based on the 2003 DAIHATSU COPEN's fuel type, age, and engine size, these are the most likely problem areas to check.

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.

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.
