About the 2004 SEAT AROSA
The 2004 SEAT AROSA is a city car with a 998cc petrol engine. 1,092 of these vehicles were MOT tested in 2026, making it a reasonably common sight on UK roads. Among all cars from 2004, the average MOT pass rate is 72%, and this model beats that benchmark.
With an average of 73,523 miles at 22 years old, SEAT AROSA 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.
2004 SEAT AROSA Fuel Costs
The modest 998cc 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 2004 SEAT AROSA?
Total estimated annual running cost is £1,530 (£128/month), broken down as £955 fuel, £20 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 74% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 2004 SEAT AROSA
At 22 years old, the SEAT AROSA 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 1998 model has the highest pass rate at 76%.
Common Issues to Watch For
Based on the 2004 SEAT AROSA's fuel type, age, and engine size, these are the most likely problem areas to check.
Coil Pack Failure
Medium riskSmaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.
Rust and Corrosion
Watch outAt 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 outRubber 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 riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
