To estimate the price of the 2020 Toyota Hilux I4 2.7L GLX Single Cab 4WD (Mid++), I considered the listed prices of similar cars. The closest match is a 2020 Toyota Hilux I4 2.7L GLX Single Cab 4WD (Mid++) with the same mileage listed for SAR 59000. Another similar car with lower mileage (93000 km) was listed for SAR 67000. Given the higher mileage of the target car (198000 km), it is reasonable to expect a lower price. The other listings, such as the 2020 Toyota Hilux GL 2 Double Cab 4WD (Diesel) with higher mileage (237000 km) listed for SAR 66000, and the 2019 Toyota Hilux S GLX I4 2.7L with even higher mileage (275800 km) listed for SAR 78000, suggest that the price should be adjusted downwards for higher mileage. Considering these factors, I estimate the market price to be slightly lower than the SAR 59000 listing due to the high mileage and average condition.
