To estimate the price of the 2014 GMC Terrain I4 2.4L SLE1 in bad condition, I first considered the selling prices of similar cars. The 2014 GMC Terrain SLT AWD 3.6L V6 in good condition sold for AED 25000, and the 2012 GMC Terrain 2.4L I4 in average condition sold for AED 21000. Given the target car's bad condition and higher mileage, its value should be lower. I also looked at listed prices: a 2014 Terrain SLE2 with 240500 km was listed for AED 18000, and a 2013 SLT V6 with 221200 km was listed for AED 16000. Considering the target car's base variant and bad condition, I estimate its market price to be lower than these listings.
