To estimate the price of the 2013 Hyundai Elantra I4 1.8L GL (Base) in bad condition, I considered several data points. The closest match in terms of variant and specs is the 2013 Hyundai Elantra GT 1.8L i4, which had an offer accepted at AED 19000 and is listed for AED 21000. However, the target car is in bad condition and has higher mileage (120780 miles vs. 49300 miles). The classified listings for similar 2013 Elantras range from AED 16000 to AED 21000, with the most relevant being AED 16000 and AED 17000 for cars with similar mileage. Given the bad condition and higher mileage, I adjusted the price downwards from these listings.
