About the 2004 PORSCHE 911 CARRERA 4S

The 2004 PORSCHE 911 CARRERA 4S is a luxury with a 3600cc petrol engine. 32 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 5% of all 2004 cars for reliability.

With an average of 69,237 miles at 22 years old, PORSCHE 911 CARRERA 4S 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 PORSCHE 911 CARRERA 4S Fuel Costs

The 3600cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,592 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 PORSCHE 911 CARRERA 4S?

Total estimated annual running cost is £2,607 (£217/month), broken down as £1592 fuel, £760 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 94% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Buying a Used 2004 PORSCHE 911 CARRERA 4S

At 22 years old, the PORSCHE 911 CARRERA 4S 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 32 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 2004 PORSCHE 911 CARRERA 4S's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 22 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.

Oil Consumption

Medium risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

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.
