To estimate the price of the 2017 BMW 420 2.0L I4 Standard sedan with 74000 km mileage, I first considered the selling price of a similar car: a 2016 BMW 420 Sport 2.0L I4 Standard sedan with 85500 km, which sold for AED 64000 on 2024-01-07. Given the one-year difference and slightly higher mileage, I adjusted the price upwards slightly. Next, I looked at offers accepted by sellers for similar models: a 2017 BMW 420 Gran Coupe 2.0L I4 Twin Turbo M Kit with 91500 km had an accepted offer of AED 73000, and a 2017 BMW 420 2.0L Turbo I4 M Kit convertible with 67000 km had an accepted offer of AED 84000. These offers are higher due to the M Kit variant and different body types. For listed prices, a 2017 BMW 420 2.0L I4 Standard sedan with 74000 km was listed for AED 80000, but listed prices are generally higher than selling prices. Considering all data points, I estimated the market price by balancing the actual selling price, accepted offers, and listed prices, while accounting for the car's condition and mileage.
