To estimate the price of the 2015 Geely EC 8 I4 2.4L Standard with 34000 km mileage, I first looked at the selling prices of similar cars. The 2015 Geely EC 8 I4 2.0L with 34500 km sold for 25000 SAR on 2023-08-08. The 2013 Geely EC 8 I4 2.0L with 164500 km sold for 17500 SAR on 2023-09-28. Given the lower mileage and newer model year of the target car, it should be valued higher than the 2013 model. Next, I considered the listed prices: a 2015 Geely EC 8 I4 2.4L Standard with 178000 km is listed for 20500 SAR, and a 2015 Geely EC 8 I4 2.4L GS (Top) with 226000 km is listed for 13500 SAR. The target car has significantly lower mileage, which increases its value. Considering these factors, I estimated the market price.
