The car to be estimated is a 2012 Mercedes G55 AMG V8 5.5L Super Charged Standard with 169000 km mileage. The only data point available is a listed price of a similar car: a 2012 Mercedes G55 AMG V8 5.4L Supercharged Standard with 162000 km mileage listed for SAR 220000. Given that listed prices are generally higher than actual selling prices, I will adjust the price downwards. Considering the mileage difference and the average condition of the car in question, I estimate a reduction of around 10%. Therefore, the estimated price is SAR 198000.
