To estimate the price of the 2020 Mercedes S560 V8 4.0L Twin Turbo Standard coupe with 50000 km mileage and Canadian specs, I considered the following data points: 1. A 2020 Mercedes S560 V8 4.0L Twin Turbo convertible with 27700 km and American specs listed for SAR 408000. 2. A 2020 Mercedes S560 Designo V8 4.0L Twin Turbo sedan with 73000 km and American specs listed for SAR 315000. 3. A 2018 Mercedes S560 V8 4.0L Twin Turbo sedan with 49500 km and American specs listed for SAR 232000. 4. A 2019 Mercedes S560 V8 4.0L Twin Turbo sedan with 45000 km and American specs listed for SAR 232500. Considering the car's condition, mileage, and specs, I adjusted the prices accordingly. The convertible's higher price reflects its body type, while the sedan prices are lower. The Canadian specs might slightly lower the price compared to American specs. The average of the listed prices is around SAR 296875. Given the car's good condition and mileage, I estimate the market price to be slightly higher than the average of the sedans but lower than the convertible.
