I started by examining the selling prices of similar cars. The most relevant data points are the two 2020 Mitsubishi Attrage 1.2L I3 Standard variants sold for AED 23000, with mileages of 111000 km and 62700 km. The car with 61000 km, a GLX LL (Mid) variant, sold for AED 22000. Given the target car's mileage of 83500 km, it is closer to the 62700 km car but with higher mileage, suggesting a slightly lower price than AED 23000. Next, I considered offers accepted by sellers. The most relevant accepted offer for a Standard variant with 84000 km was AED 23000, which aligns with the selling prices. Other accepted offers for similar mileages were around AED 22000 to AED 27000, but the most recent and relevant offer was AED 23000. Considering these data points, the estimated market price for the target car is AED 23000.
