2011 Hyundai I10 1.2L Petrol · WJ11 AAZ

The 1.25-litre petrol i10 is a frugal car, with real-world fuel economy typically in the 45-50 mpg range for mixed driving, translating to roughly £1,200-£1,500 in annual fuel costs at current prices for around 7,000 miles of use. Road tax falls into a low band given the small engine and 2011 registration, so VED is likely to be modest, though post-2017 rules do not apply. Insurance is one of the i10's strongest selling points, sitting in a low group, which should keep premiums in the £300-£500 region for an experienced driver.

Maintenance costs are generally low, with parts being inexpensive and the Kappa engine being mechanically straightforward. However, the recent MOT failures suggest some remedial work has been carried out or will be required, and a 15-year-old car at 75,000 miles may soon need items such as a new battery, tyres, brake discs, or exhaust components. Estimated annual maintenance, including routine servicing and consumables, is likely in the £300-£500 bracket for a car of this age, but set aside a contingency for the lambda/catalyst issue if it resurfaces. Overall estimated annual running cost is approximately £800-£1,100, depending on mileage and whether any major work is needed.

Begin with a cold start to check for any engine warning lights, rough idle, or excessive smoke from the exhaust, as the lambda reading failure could indicate a failing catalytic converter or upstream oxygen sensor. Listen for any rattling on startup which might suggest a loose heat shield or internal catalyst failure. Ask the seller to demonstrate the headlamp aim and confirm the recent MOT pass was a genuine retest after repair rather than a partial pass with deferred items. Check the front registration plate condition, as it has now been flagged three times across two tests.

Physically inspect the rear shock absorbers for visible corrosion, oil seepage, or any signs of recent replacement, given the repeated advisories in 2024 and 2025. Push down firmly on each corner of the car and release; the car should rebound once and settle, not bounce repeatedly, which would indicate worn dampers. Examine the offside front brake for the binding issue noted in 2024, checking for a hot wheel after a test drive and any pulling to one side under braking. The nearside front brake pads were flagged as wearing thin in 2024, so verify they have been replaced and inspect the discs for lipping or scoring.

Finally, inspect the underside of the car on a ramp if possible, paying particular attention to exhaust integrity, suspension arms (the most common i10 MOT failure point according to aggregate data), and any signs of accident damage or poor previous repairs. Check the sills, wheel arches, and subframe for corrosion, as small city cars of this age are not immune to rust, particularly around the rear arches and underbody seams. A thorough inspection of the headlamp lenses is worthwhile, as headlamp failures are the single most common MOT issue for the i10 model overall.
