I started by looking at the selling prices of similar used cars. The closest match to the car in question is the 2020 Toyota Land Cruiser V8 4.6L GXR4 with 91000 km, which sold for 335000 SAR on 2023-10-12. This car is a mid+++ variant, while the car in question is a top variant, which generally commands a higher price. Another relevant data point is the 2021 Toyota Land Cruiser V8 4.6L GXR3 4.6L (Mid++) with 99000 km, which sold for 223000 SAR on 2023-11-12. Given that the car in question is a 2020 model with 80500 km, it should be priced higher than the 2021 model due to its lower mileage and higher trim level. The 2020 Toyota Land Cruiser V8 4.6L GXR3 LS (Mid+++) with 164000 km sold for 207000 SAR on 2024-02-05, but it has significantly higher mileage. Considering these factors, I adjusted the price upwards for the lower mileage and higher trim level of the car in question.
