To estimate the price of the 2021 Land Rover Defender 110 X-DYNAMIC HSE V6 3.0L Turbo Charged (P400), I considered the listed prices of similar cars. The closest match is the 2021 Land Rover Defender 110 X P400 V6 3.0L Supercharged with 62300 km listed for SAR 335500. Given that the target car has higher mileage (71000 km) and is a mid+ variant, I adjusted the price downwards. The 2020 Land Rover Defender I4 2.0L Turbocharged 110 HSE (P400) with 52500 km is listed for SAR 248000, and the 2020 model with 39500 km is listed for SAR 252500. These are lower trims and older models, so their prices are lower. The 2022 Land Rover Defender 110 X I6 3.0L Turbocharged with 42000 km is listed for SAR 440000, but it is a newer model and a higher trim. Considering these factors, I estimated the price of the target car to be slightly lower than the 2021 model with lower mileage but higher than the 2020 models.
