To estimate the price of the 2014 Volkswagen Passat I5 2.5L S (Base) with 206500 km mileage and average condition, I considered the following data points: 1) A similar 2014 Passat 2.5L I5 Sport (Top) with 197500 km sold for AED 18500 on 2024-06-13. 2) A 2014 Passat 2.5L I5 SE (Mid) with 140500 km sold for AED 18000 on 2024-02-16. 3) A 2015 Passat 2.5L I5 SE (Mid) with 212500 km sold for AED 16500 on 2024-02-22. 4) A 2013 Passat 2.5L I4 SE (Mid) with 200063 km sold for AED 15500 on 2024-07-07. 5) An offer accepted for a 2014 Passat 2.5L V6 SE (Mid) with 200000 km was AED 16000 on 2023-11-07. 6) A listed price for a 2014 Passat I5 2.5L S (Base) with 206500 km was AED 16000. Considering the car's base variant and higher mileage, I adjusted the price slightly lower than the Sport and SE variants but higher than the 2013 model.
