The car in question is a 2011 Lincoln MKX V6 3.7L 2.7T Reserve with 137600 km mileage. We have limited data, primarily from listed prices. A 2012 Lincoln MKX 3.7L V6 Base with 134200 km is listed for AED 21000. Classified ads show a 2012 model with 67000 km listed for AED 30000, and two others with higher mileage (215000 km and 219000 km) listed for AED 22000 and AED 21000 respectively. The car in question is a higher trim (Reserve) than the Base model listed for AED 21000, which suggests a higher value. However, the mileage is higher than the 67000 km car listed for AED 30000. Considering the trim and mileage, a reasonable estimate would be slightly above the AED 21000 listing but below AED 30000, accounting for the higher trim and average condition.
