To estimate the price of the 2021 Nissan Patrol LE Platinum V8 5.6L with 39000 km mileage, I first looked at the selling prices of similar cars. The closest match in terms of variant and engine size is the 2023 Nissan Patrol Platinum V6 4.0L with 500 km, sold for 259500 SAR on 2023-12-27. Adjusting for the older model year and higher mileage, I considered a depreciation. Another relevant data point is the 2023 Nissan Patrol V8 5.6L Nismo with 3000 km, sold for 315000 SAR on 2024-04-29. Given the Nismo variant is higher-end, I adjusted downwards. The 2021 Nissan Patrol V6 4.0L with 63000 km sold for 177000 SAR on 2023-09-09, and the 2021 Nissan Patrol V6 4.0L with 104000 km sold for 139000 SAR on 2023-10-16, both of which are lower trims and engine sizes. Considering the listed price of a similar 2021 Nissan Patrol LE Platinum V8 5.6L at 204000 SAR, I adjusted slightly downwards to account for negotiation and market conditions.
