To estimate the price of the 2014 Mercedes S500 V8 4.7L BiTurbo Top, I first considered the offer accepted for a similar 2014 Mercedes S500 V8 4.7L with a mileage of 205458, which was SAR 118000 on 2023-12-09. This car is similar in age and engine size but has a higher mileage and is a standard variant, which typically sells for less than the top variant. Next, I looked at the listed prices for 2015 models: a standard variant with 173000 miles listed for SAR 138000 and an AMG top variant with 120000 miles listed for SAR 194500. The target car is a top variant, which should be priced higher than the standard variant but lower than the AMG variant. Considering the higher mileage of the target car (193246 miles) compared to the listed 2015 models, I adjusted the price downwards. The accepted offer of SAR 118000 for a similar 2014 model with higher mileage and lower trim suggests a slightly higher price for the target car due to its top variant status, but the high mileage and average condition warrant a conservative estimate.
