To estimate the price of the 2019 Honda City DX (Base) with 100000 km mileage, I considered several data points. First, the selling prices of similar cars: a 2017 Honda City LX (Mid) with 161500 km sold for 22000 AED, a 2021 Honda City DX (Base) with 32500 km sold for 48000 AED, and a 2018 Honda City DX (Base) with 102300 km sold for 32500 AED. The 2018 model is closest in terms of variant and mileage, suggesting a price around 32500 AED. Next, an offer accepted for a 2019 Honda City LX (Mid) with 109500 km was 38000 AED, and a dealer sold a 2019 Honda City LX with 77198 km for 46741.5 AED. Listed prices for 2019 Honda City DX (Base) models were 34000 AED, 54990 AED, and 45000 AED, but these are generally higher than actual selling prices. Considering the car's condition and mileage, I adjusted the estimate slightly lower than the 2018 model's selling price and the accepted offer for the 2019 model.
