About the 2003 Proton Satria
The 2003 Proton Satria is a family car. Our records list a 1834cc petrol engine, though engines vary between versions. 36 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2003, the average MOT pass rate is 72%, and this model matches that benchmark.
With an average of 66,005 miles recorded at its 2024 MOT tests, Proton Satria 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 Proton Satria Fuel Costs
The 1834cc petrol engine offers a reasonable balance between performance and economy. Expect around 36 mpg in mixed driving, which works out to roughly £1,631 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 2003 Proton Satria?
Total estimated annual running cost is £2,511 (£209/month), broken down as £1,631 fuel, £325 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 72% pass rate. Keeping on top of servicing will help avoid surprises.
Buying a Used 2003 Proton Satria
At 23 years old, the Proton Satria 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 36 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.
Timing Chain / Belt
Watch outAt 23 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.
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.
