Insight summary

KIA Optima is a scarce model in this snapshot, with 10,124 represented vehicles and 0.02% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 82.6% from 68,052 MOT tests, with a reliability score of 51. The current pool shows an average of 90,751 miles and an average age of 8.6 years, while mature-fleet mileage is estimated at 99,760 miles. Diesel leads the fuel split, followed by hybrid electric, and the most frequent defect themes are windscreen damage, tyre condition and brake pads. The practical read is that the KIA Optima looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
