2016 KIA Optima 1.7L Diesel · M7 NSO

The 1.7‑litre diesel engine in the Optima typically delivers around 55‑60 mpg in mixed driving, which keeps fuel bills moderate for a vehicle of this size. Road tax for a diesel of this emission class falls into the £150‑£210 band, and the insurance group is usually around 20‑25, leading to average premiums for a driver with a clean claims record.

Maintenance on a 2016 Optima is generally straightforward, but the recent brake‑related MOT failures suggest you should set aside £300‑£500 for a brake service and possibly new rear discs and pads. Adding tyre replacement (£200‑£300) and the minor front plate repair (£30‑£50) brings the estimated annual running cost to roughly £900‑£1,200, covering fuel, tax, insurance and routine maintenance.

Inspect the rear brake system closely: look for disc scoring, pad thickness and any uneven wear that could indicate underlying caliper issues. The MOT failure recorded brake performance could not be tested, so a professional brake inspection is essential before purchase.

Examine all four tyres for tread depth, sidewall condition and uniform wear, as multiple MOTs have highlighted front tyre wear close to the legal limit. Verify that the tyre pressure monitoring system is operational, as a malfunction was recorded in the 2024 failure. Finally, check the front registration plate for legibility; although the MOT noted it was not likely to be misread, a deteriorated plate may need replacement to avoid future legal issues.
