To estimate the price of the 2022 Mercedes GLS450 V6 3.0L Twin Turbo, I first considered the listed prices of similar cars. A 2021 GLS450 with a similar engine but hybrid and 50,000 miles is listed for SAR 310,500. Another 2022 GLS450 with a standard variant and 38,055 miles is listed for SAR 415,000. The car in question is a 2022 model with 75,000 miles, which is higher mileage than the listed 2022 model. The new car price for a higher variant (GLS 500) is SAR 498,790. Considering the higher mileage and the fact that the car is a top variant, I estimate the price to be slightly lower than the listed 2022 standard variant but higher than the 2021 hybrid variant. I adjusted for mileage and variant differences to arrive at the estimate.
