To estimate the price of the 2016 Mazda CX-5 I4 2.5L Signature (Top) with 204000 km mileage, I considered the following data points: 1) A 2018 Mazda CX-5 I4 2.5L R (Mid) with 149650 km sold for SAR 58000 on 2023-10-01. Adjusting for the older model year and higher mileage, the value would be lower. 2) A 2016 Mazda CX-5 I4 2.5L Signature (Top) with 170000 km is listed for SAR 51500. Considering the higher mileage of the target car, the value would be lower. 3) A 2017 Mazda CX-5 I4 2.0L Core (Base) with 198000 km is listed for SAR 45000. Given the higher trim and mileage of the target car, the value would be slightly higher. Based on these comparisons, I adjusted the price downwards for the higher mileage and older model year.
