To estimate the price of the 2013 BMW 520 I4 2.0L Standard with 154000 km in bad condition, I considered the following data points: 1) An offer accepted for a similar car with 129000 km at AED 31000 on 2023-11-24. Given the higher mileage and worse condition of the target car, I adjusted the price downwards. 2) Listed prices of similar cars ranged from AED 26000 to AED 39000, with the most relevant being AED 26000 for a car with 155625 km and AED 27500 for a car with 170000 km. Considering the bad condition of the target car, I leaned towards the lower end of this range. 3) The car listed for AED 26000 was delisted on 2024-05-04, indicating it might have sold for around that price. Taking all these factors into account, I estimated the market price accordingly.
