About the 2011 YAMAHA UNCLASSIFIED
The 2011 YAMAHA UNCLASSIFIED is a city car with a 686cc petrol engine. 41 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 8% of all 2011 cars for reliability.
With an average of 6,017 miles at 15 years old, YAMAHA UNCLASSIFIED 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.
2011 YAMAHA UNCLASSIFIED Fuel Costs
The modest 686cc petrol engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £955 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).
What does it cost to own a 2011 YAMAHA UNCLASSIFIED?
Total estimated annual running cost is £1,230 (£103/month), broken down as £955 fuel, £20 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 95% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
YAMAHA UNCLASSIFIED Reliability Trend
Older YAMAHA UNCLASSIFIEDs tend to have better MOT pass rates than newer ones, with an average decline of 5 percentage points across model years.
Buying a Used 2011 YAMAHA UNCLASSIFIED
At 15 years old, the YAMAHA UNCLASSIFIED 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 2006 model has the highest pass rate at 100%. Note: with only 41 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2011 YAMAHA UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.
Coil Pack Failure
Medium riskSmaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.
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.
