Common Issues to Watch For

Based on the 2021 SUBARU LEGACY's fuel type, age, and engine size, these are the most likely problem areas to check.

Oil Consumption

Low risk

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

Medium risk

With an average of 93k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
