2016 Lexus IS 2.5L Hybrid electric · MK66 RYY

The first priority when viewing this car should be verifying the mileage against supporting documentation such as service invoices, previous MOT certificates, and any available service history printouts. An average of roughly 14,000 miles per year is not disastrous in isolation, but the jump from 92,861 miles in August 2024 to 142,554 miles by August 2026 is striking — that is nearly 50,000 miles covered in just two years, suggesting the car may have been used for long-distance commuting or as a high-utilisation vehicle. Ask the seller directly about the type of journeys undertaken and whether any work was carried out during that period.

On the mechanical side, Lexus IS 300h models are generally regarded as well-engineered, but hybrid batteries, inverter coolant pumps and 12V auxiliary batteries do age. A hybrid system health check at a Lexus dealer or hybrid specialist would be money well spent before purchase. Also inspect the condition of the alloy wheels, interior trim and switchgear, as these reveal how the car has been treated. Given the very high mileage, budget for replacement tyres and brake discs at the front if not recently renewed — these are wear items that have likely been replaced multiple times already.

Negotiation should focus on the upcoming major service interval and the cost of replacing the hybrid battery if it shows any sign of degradation. Lexus hybrid batteries are known to last a long time, but a ten-year-old example at this mileage is approaching the point where some owners report reduced capacity. Request any evidence of hybrid system diagnostics or battery state-of-health reports from previous services.

This is a September 2016 Lexus IS 300h finished in black, powered by a 2.5-litre petrol-electric hybrid powertrain. Five MOT tests have been recorded, all passing without any advisories or defects noted — an unusually clean record on paper. However, the vehicle has covered 142,554 miles in roughly ten years, equating to an annual average of around 14,000 miles, which is well above the 8,645-mile average observed across 12,871 examples of this model. The combination of spotless MOT results and very high mileage warrants careful investigation before committing to a purchase.
