To estimate the price of the 2017 Opel Astra 1.4TC I4 Top, I considered several data points. First, a 2015 Opel Astra 1.6L I4 TC GTC (Top+) with 63550 km sold for AED 28000 on 2024-04-29. Given the 2-year difference and higher mileage of the target car, I adjusted the price downwards. Another 2015 Opel Astra 1.6L Turbo I4 GTC (Top+) with 151500 km had an offer accepted for AED 19500 on 2024-04-24, which is closer in mileage but older. For listed prices, a 2017 Opel Astra 1.4TC I4 Top with the same mileage was listed for AED 24500, and a similar 2017 model with lower mileage (89500 km) was listed for AED 34000. Considering the average condition and higher mileage of the target car, I estimated the market price to be slightly lower than the listed price of the same model with the same mileage.
