To estimate the price of the 2015 Ford Focus I4 1.6L Standard in below average condition, I first considered the selling prices of similar cars. A 2014 model with similar specs and average condition sold for SAR 20,000 and SAR 15,000, while a 2013 model sold for SAR 16,000. These cars were in average condition, so I adjusted for the below average condition of the target car, reducing the estimate by about 20%. This suggests a price around SAR 12,800 to SAR 16,000. Next, I looked at listed prices. A 2015 model with higher mileage was listed for SAR 28,500, but this is likely higher than the selling price. A 2014 model with similar mileage was listed for SAR 19,000. Considering the condition and typical negotiation, the selling price would be lower. Combining these insights, I estimated the market price for the target car.
