To estimate the price of the 2015 Hyundai Elantra I4 1.8L GL (Base) in bad condition, I first considered the selling prices of similar cars. A 2015 Elantra 2.0L GLS (Top) in good condition sold for AED 28000, and a 2013 Elantra 2.0L GL (Base) in average condition sold for AED 15500. The 2015 Elantra GLS 1.8L had an accepted offer of AED 21000. The listed prices for 2015 Elantra GL (Base) variants range from AED 16000 to AED 23000, with higher mileage cars listed at lower prices. Given the bad condition and high mileage of the target car, I estimate its market price to be lower than the lowest listed price, around AED 14000.
