About the 1990 Porsche 944

The 1990 Porsche 944 is a luxury car. Our records list a 2969cc petrol engine, though engines vary between versions. 914 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. Among all models from 1990, the average MOT pass rate is 79%, and this model beats that benchmark.

With an average of 125,016 miles recorded at its 2024 MOT tests, Porsche 944 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.

1990 Porsche 944 Fuel Costs

The 2969cc 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 £1,958 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 1990 Porsche 944?

Total estimated annual running cost is £2,738 (£228/month), broken down as £1,958 fuel, £375 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 85% pass rate. Keeping on top of servicing will help avoid surprises.

The Porsche 944 has maintained consistent MOT pass rates across model years, varying by only 1 percentage point.

Buying a Used 1990 Porsche 944

At 36 years old, the Porsche 944 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 1992 model has the highest pass rate at 89%.

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 out

At 36 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.

Clutch Wear

Watch out

With an average of 125k 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.

Engine Mounts

Medium risk

Worn engine mounts cause excessive vibration and movement. Replacement costs £150-£400 per mount. Check for vibration at idle with the bonnet open.

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.
