The car in question is a 2023 BMW 420 I4 2.0L Twin Power Turbo (M Kit) Standard sedan with 20500 km mileage. We have two listed prices for similar cars: a 2023 BMW 420 with 19000 km listed at SAR 174000 and a 2021 BMW 420 with 73000 km listed at SAR 192500. The 2023 model is more relevant due to the same year and similar mileage. The listed price of SAR 174000 for the 2023 model is likely higher than the actual market value, as listings are often above selling prices. Considering the sedan body type might be slightly less valuable than a coupe, and the mileage is slightly higher, I estimate the market price to be slightly lower than SAR 174000.
