First, I considered the selling prices of similar cars. A 2017 Mercedes G63 AMG with 73,000 km sold for 350,000 SAR in October 2023. Another 2015 model with 171,000 km sold for 175,000 SAR in April 2024. The 2017 model is more relevant due to the closer year and mileage. Next, I looked at listed prices: a 2017 model with 73,000 km is listed for 350,000 SAR, a 2016 model with 108,000 km is listed for 277,000 SAR, and a 2015 model with 171,000 km is listed for 189,000 SAR. Given the Brabus Kit and lower mileage (69,082 km) of the target car, it should be valued higher than the standard 2017 model. Considering these factors, I adjusted the price upwards from the 350,000 SAR benchmark.
