To estimate the price of the 2017 Range Rover Vogue SE V8 5.0L Supercharged with 142000 km mileage, I considered the listed prices of similar cars. The 2016 model with 90000 km is listed for SAR 160000, the 2018 model with 63000 km is listed for SAR 301000, and the 2019 model with 35000 km is listed for SAR 394000. Given the higher mileage and older model year of the target car, I adjusted the price downwards. The 2016 model is the closest in terms of age but has significantly lower mileage, so I estimated a lower price for the 2017 model with higher mileage.
