To estimate the price of the 2016 BMW 520 2.0L I4 Standard, I first considered the offers accepted by sellers for similar cars. The offers for the Standard variant ranged from AED 49000 to AED 63500, with the most recent offer being AED 58500 for a car with 120000 km mileage. The car in question has a higher mileage of 140650 km, which suggests a lower value. Next, I looked at the listed prices of similar cars, which ranged from AED 47500 to AED 59000. The car with the closest mileage (134034 km) was listed for AED 47500. Considering the higher mileage and average condition of the car in question, I estimated the market price to be slightly lower than the lower end of the accepted offers and listed prices.
