To estimate the price of the 2018 Nissan Patrol Platinum V6 4.0L LE Platinum City (Top+), I first looked at the selling prices of similar cars. The most relevant data point is a 2018 Nissan Patrol V6 4.0L LE Platinum City (Top+) with 100000 km mileage sold for 135000 SAR on 2024-02-19. This car is very similar in terms of model, variant, and condition. Other data points include a 2017 Nissan Patrol V8 5.6L LE (Mid++) sold for 140000 SAR on 2023-10-02, and a 2017 Nissan Patrol SE V6 4.0L SE (Base+) sold for 113000 SAR on 2023-11-27. These cars are less relevant due to different engine sizes and variants. The listed prices of similar cars include a 2018 Nissan Patrol Platinum V6 4.0L LE Platinum City (Top+) with 91000 km listed for 170000 SAR and another with 100000 km listed for 150000 SAR. Considering the selling price of the most similar car (135000 SAR) and the listed prices, I estimate the market price to be slightly lower than the highest listed price but higher than the selling price due to the lower mileage and good condition.
