To estimate the price of the 2019 BMW 520 Twin Turbo I4 2.0L Standard with 49000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2020 model with 2800 km sold for 145000 AED, a 2020 model with 69500 km sold for 112500 AED, and a 2018 model with 160000 km sold for 69000 AED. The 2019 model with 39500 km had an accepted offer of 140500 AED, while another 2019 model with 81000 km had an accepted offer of 60000 AED. Listed prices for similar 2019 models ranged from 62000 AED to 145500 AED. Given the mileage and condition of the target car, I weighted the most recent and relevant data points, particularly the accepted offer of 140500 AED for a similar 2019 model with slightly lower mileage and the selling price of 112500 AED for a 2020 model with higher mileage. This led me to estimate the market price accordingly.
