About the 2015 MORGAN ROADSTER
The 2015 MORGAN ROADSTER is a performance with a 3721cc petrol engine. 58 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2015, the average MOT pass rate is 83%, and this model beats that benchmark.
With an average of 12,890 miles at 11 years old, MORGAN ROADSTER 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.
2015 MORGAN ROADSTER Fuel Costs
The 3721cc 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 2015 MORGAN ROADSTER?
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 91% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
MORGAN ROADSTER Reliability Trend
The MORGAN ROADSTER has maintained consistent MOT pass rates across model years, varying by only 2 percentage points.
Buying a Used 2015 MORGAN ROADSTER
At 11 years old, the MORGAN ROADSTER 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 2004 model has the highest pass rate at 100%. Note: with only 58 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2015 MORGAN ROADSTER's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 11 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 riskLarger 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 outAt 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 outRubber 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 riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
