To estimate the price of the 2023 Nissan Altima I4 2.5L SV (Mid+), I first looked at the selling prices of similar cars. A 2023 Altima SV (Mid+) with 13000 km sold for 108000 SAR on 2024-05-18. This car is very similar to the target car but has lower mileage. Another 2022 Altima S (Base) with 26078 km sold for 73500 SAR on 2024-03-21, and a 2021 Altima SL (Top) with 37000 km sold for 75000 SAR on 2024-06-23. The new car price for a 2024 Altima SV is 123385 SAR. Considering the target car's mileage of 20000 km and its good condition, I adjusted the price slightly lower than the similar car sold for 108000 SAR due to the higher mileage. The listed price of a similar car with the same mileage is 93500 SAR, which is lower than the selling price of the similar car. Taking all these factors into account, I estimated the market price accordingly.
