To estimate the price of the 2019 Mazda CX-5 I4 2.5L Signature (Top) with 120599 km mileage, I first considered the selling prices of similar cars. A 2019 model with the same variant and higher mileage (161500 km) sold for 65000 SAR on 6 Nov 2024. Another 2019 model with lower mileage (40000 km) sold for 88000 SAR on 10 Mar 2024. These provide a range of 65000 to 88000 SAR. The listed prices for similar cars are 80000 SAR for cars with lower mileage (100000 km and 83367 km) and 65000 SAR for a car with the same mileage as the sold one. Given the target car's mileage is between these examples, and considering the market trend, I estimate the price to be slightly above the lower end of the sold range, accounting for the higher mileage compared to the 88000 SAR car.
