To estimate the price of the 2016 Toyota Camry I4 2.5L GL LE STD (Base) with 158000 km mileage and average condition, I considered several data points. First, I looked at the selling prices of similar cars. The 2015 Camry LE STD (Base) with 207380 km sold for 36300 SAR on 2023-09-13. The 2017 Camry LE STD (Base) with 212080 km sold for 39500 SAR on 2023-09-07, and another 2017 Camry LE STD (Base) with 109000 km sold for 52000 SAR on 2024-02-29. The 2016 Camry SE (Top) with 299835 km sold for 43000 SAR on 2024-06-12. The 2016 Camry LE STD (Base) with 167700 km was listed for 37000 SAR but delisted on 2023-08-28. Considering the average condition and mileage of the target car, I weighted the prices of similar base models more heavily. The average selling price of the base models is around 39300 SAR. Given the target car's slightly lower mileage and the fact that it is a 2016 model, I adjusted the estimate slightly higher.
