To estimate the price of the 2017 Hyundai Elantra 2.0L I4 GL (Base) in bad condition, I considered several data points. First, I looked at the selling prices of similar cars: a 2016 Elantra GT in average condition sold for AED 16000 and a 2019 Elantra GL (Base) in average condition sold for AED 31500. Given the target car's bad condition, its value should be lower. Next, I reviewed offers accepted by sellers: a 2017 Elantra GL (Base) with 56550 miles had an offer accepted at AED 30000, and another 2017 Elantra GL (Base) with 65500 miles had an offer accepted at AED 27500. These offers are higher than the selling prices due to better conditions. Lastly, I checked listed prices: a 2017 Elantra GL (Base) with 56550 miles was listed for AED 30500, and another with 56200 miles was listed for AED 31500. Considering the bad condition of the target car, I adjusted the price downwards from these figures.
