To estimate the price of the 2019 Mercedes S450 V6 3.0L Twin Turbocharged Top with 114000 miles, I considered the listed prices of similar cars. The closest match in terms of variant and year is the 2019 Mercedes S450 V6 3.0L Twin Turbo, Top variant with 56000 miles listed for SAR 282500. Given the higher mileage of the target car, I adjusted the price downwards. Other 2019 models with higher mileage (130000 miles) were listed for SAR 306000, and with lower mileage (71444 miles) for SAR 317000. The 2018 models with similar mileage (124000 miles) were listed for SAR 205000 and SAR 199000. Considering the target car's mileage and condition, I estimated the price to be slightly lower than the 2019 Top variant with lower mileage but higher than the 2018 models with similar mileage.
