Given the lack of specific data points such as selling prices, offers accepted, and listed prices of similar cars, I will use the new car price and apply depreciation logic. Assuming a new 2015 FIAT 500L I4 1.4L Turbocharged Trekking (Top) was priced at approximately 100,000 SAR, and considering a depreciation rate of 10% per year over 9 years, the estimated value would be calculated as follows: 100,000 SAR * (0.9^9) = 38,742 SAR. Adjusting for the car's good condition and mileage, the final estimate is rounded to 39,000 SAR.
