The car in question is a 2015 Toyota Zelas I4 2.5L Standard with 139,000 km mileage. We have an offer accepted for a 2014 model with higher mileage (185,000 km) at AED 19,500. This suggests a lower bound for the 2015 model. A 2015 model with higher mileage (182,713 km) is listed at AED 29,000, and a 2014 model with lower mileage (135,000 km) is listed at AED 28,000. Considering the 2015 model's average condition and mileage, a reasonable estimate would be slightly above the accepted offer for the 2014 model but below the listed prices, accounting for negotiation and market conditions.
