About the 2005 YAMAHA YFM 660
The 2005 YAMAHA YFM 660 is a city car with a 660cc petrol engine. 38 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 2% of all 2005 cars for reliability.
With an average of 4,261 miles at 21 years old, YAMAHA YFM 660 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.
2005 YAMAHA YFM 660 Fuel Costs
The modest 660cc 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 2005 YAMAHA YFM 660?
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 97% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
Buying a Used 2005 YAMAHA YFM 660
At 21 years old, the YAMAHA YFM 660 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. Note: with only 38 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2005 YAMAHA YFM 660'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.
