To estimate the price of the 2015 Hyundai i30 I4 1.8L GL (Base) hatchback, I first considered the selling prices of similar cars. A 2016 Hyundai i30 1.8L hatchback with similar specs and condition sold for AED 20,000 on 15 Sep 2024 and AED 17,500 on 17 Nov 2024. Given the 2015 model is older, I expect a lower price. The 2016 model with a 1.6L engine sold for AED 15,000, but the 1.8L engine is more comparable. The listed prices for similar 2016 models range from AED 18,500 to AED 21,500, but these are generally higher than selling prices. Considering the 2015 model's higher mileage of 221,500 km compared to the 2016 models, I adjusted the price downwards. The 2015 GLS (Top) variant listed for AED 21,500 is not directly comparable due to its higher trim. Based on these factors, I estimated the market price for the 2015 model to be slightly lower than the lowest 2016 selling price.
