About the 2014 BENTLEY MULSANNE

The 2014 BENTLEY MULSANNE is a luxury with a 6752cc petrol engine. 237 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It ranks in the top 3% of all 2014 cars for reliability.

With an average of 41,306 miles at 12 years old, BENTLEY MULSANNE 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.

2014 BENTLEY MULSANNE Fuel Costs

Buying a Used 2014 BENTLEY MULSANNE

At 12 years old, the BENTLEY MULSANNE 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 2018 model has the highest pass rate at 100%.

Common Issues to Watch For

Based on the 2014 BENTLEY MULSANNE's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 12 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.
