To estimate the price of the 2014 Lincoln Navigator 5.4L V8 Standard with 166000 km mileage, I considered the listed prices of similar cars. The closest match is a 2014 Lincoln Navigator V8 5.4L 4WD, Variant: Presidential (Top), with 120646 km listed for AED 37000. Given that the car in question has higher mileage and is in average condition, I adjusted the price downwards. The other listed prices for 2016 models range from AED 69500 to AED 118000, but these are newer models with lower mileage and different variants. Therefore, the most relevant data point is the 2014 model listed at AED 37000, and I adjusted for the higher mileage and average condition.
