I started by examining the offers accepted by sellers for similar cars. The closest match is the 2020 Mercedes E450 3.0 V6 with 76000 km, non-GCC specs, which had an offer accepted at AED 195000 in May 2024. This car is very similar to the target car in terms of year, engine, and body type, but has slightly lower mileage. Another relevant data point is the 2019 Mercedes E450 3.0 V6 TC with 60050 km, which had an offer accepted at AED 118000 in March 2024. This car is older and has higher mileage, which suggests a lower value. The listed price for a similar 2020 model with 76000 km was AED 195500, which aligns with the accepted offer. Considering the target car's mileage of 80500 km and Japanese specs, I estimate the market price to be slightly lower than the AED 195000 offer due to higher mileage and non-GCC specs.
