Buying a Used 2012 TOYOTA IQ
At 14 years old, the TOYOTA IQ 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 2014 model has the highest pass rate at 91%.
Common Issues to Watch For
Based on the 2012 TOYOTA IQ'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.
