I started by looking at the selling prices of similar 2016 Nissan Maxima V6 3.5L cars. The most relevant data points are: 1) A 2016 Maxima S (Base) with 157300 km sold for 43000 SAR on 2023-10-30. 2) Another 2016 Maxima S (Base) with 122500 km sold for 32500 SAR on 2023-12-26. 3) A 2016 Maxima SV (Mid) with 208000 km sold for 41000 SAR on 2024-07-05. Given that the car in question has 209500 km, which is higher than the average mileage of the cars sold, and considering the condition is average, I adjusted the price slightly lower than the 43000 SAR and 41000 SAR benchmarks. The 32500 SAR car had significantly lower mileage, so it was less relevant. Therefore, I estimated the price to be slightly below the 41000 SAR mark.
