The most relevant data point is the offer accepted for a 2018 BMW 520 2.0L I4 TwinTurbo Standard with similar mileage and specs, which was AED 68000 on 2024-07-19. This is a strong indicator of the market value. The selling price of a similar car with a different variant (M Sport) was AED 69000, but it had higher mileage. Listed prices for similar cars range from AED 73000 to AED 110000, but these are generally higher than actual selling prices. Considering the accepted offer and the selling price, the estimated market price should be slightly below AED 68000 to account for negotiation and market conditions.
