2014 KIA Optima 1.7L Diesel · MT64 ADV

Real-world fuel economy for the 1.7-litre CRDi diesel typically sits in the mid-50s mpg on a run, dropping into the low-40s around town. As a diesel registered between 2010 and 2015, this Optima falls into a higher first-year VED band, though subsequent years are charged at the standard flat rate of around £20. Insurance is usually group 20-22 depending on trim, which is moderate for an executive saloon of this size.

Maintenance costs are likely to rise given the advisory pattern in the MOT history. Budget for front and rear brake discs and pads together with a full set of matching tyres, which could collectively cost £700-£900 at an independent specialist. With an estimated annual mileage in line with the recorded average, total yearly running costs including fuel, tax, insurance and maintenance are likely to fall in the £1,400-£1,800 range.

Start with a physical inspection of the front and rear brake discs, as pitting and scoring has been flagged at three consecutive MOTs. Measure disc thickness against the manufacturer's minimum specification rather than relying solely on visual judgement, and check the pads for remaining material. Inspect all four tyres for uneven shoulder wear, particularly on the nearside and offside fronts, since both were reported as edge-worn in December 2025.

Lift the car and check for oil leaks from the 1.7-litre CRDi diesel, paying particular attention to the turbo oil feed and return pipes, the cam cover gasket and the oil filter housing. Examine the rear wheel on the offside for distortion, as a slightly distorted rim was noted in 2022. Finally, ask the seller to demonstrate that all dashboard warning lights extinguish correctly on startup and request a diagnostic read for any stored fault codes, especially relating to the emissions equipment, DPF, and EGR valve on this diesel variant.
