To estimate the price of the 2014 Range Rover HSE 5.0L V8 520PS V8 (Top) with 256000 km mileage, I first looked at the selling prices of similar cars. The 2016 model with 207600 km sold for 93500 AED and another 2016 model with 139500 km sold for 98500 AED. A 2012 model with 206500 km sold for 33000 AED. Considering the age and mileage, the 2014 model should be priced lower than the 2016 models but higher than the 2012 model. Next, I reviewed the listed prices of similar cars. A 2014 model with 256000 km was listed for 69500 AED, and another 2014 model with 244500 km was listed for 83000 AED. Given the condition and mileage, the price should be closer to the lower end of these listings. Finally, I considered the depreciation and market trends to arrive at a fair estimate.
