About the 2018 Rolls-Royce Phantom

The 2018 Rolls-Royce Phantom is a luxury car. Our records list a 6749cc petrol engine, though engines vary between versions. 253 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. It ranks in the top 1% of all 2018 models for MOT pass rate.

With an average of 20,728 miles recorded at its 2024 MOT tests, Rolls-Royce Phantom 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.

2018 Rolls-Royce Phantom Fuel Costs

The 6749cc 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 2018 Rolls-Royce Phantom?

Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 100% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Rolls-Royce Phantom Reliability Trend

The Rolls-Royce Phantom has maintained consistent MOT pass rates across model years, varying by only 2 percentage points.

Buying a Used 2018 Rolls-Royce Phantom

At 8 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage.

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 8 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.

Suspension Wear

Medium risk

Shock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.

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.
