To estimate the price of the 2018 Nissan Maxima SV 3.5L V6 in bad condition with 157800 miles, I first looked at the selling price of a similar 2018 Nissan Maxima 3.5L V6 SR (Top) with 84581 miles in average condition, which sold for AED 40000 on 2023-11-19. Given the higher mileage and worse condition of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars: a 2017 Maxima SV with 138031 miles listed for AED 45000, and a 2018 Maxima SR with 87600 miles listed for AED 43500. Considering the target car's higher mileage and worse condition, I further adjusted the price downwards. Finally, I considered the depreciation and condition differences to arrive at a fair market estimate.
