To estimate the price of the 2010 Nissan Patrol XE (Base) with 186000 km mileage and average condition, I considered the following data points: 1. Selling prices: A 2012 LE Platinum (Top+++) with 275450 km sold for AED 46000, a 2011 LE Titanium (Top++) with 187100 km sold for AED 51000, and a 2010 LE Platinum (Top+++) with 261000 km sold for AED 53500. These variants are higher trims than the XE (Base). 2. Accepted offers: A 2010 LE Platinum (Top+++) with 230000 km had an accepted offer of AED 55000. 3. Listed prices: A 2012 LE Platinum (Top+++) with 202900 km listed for AED 46000, a 2012 XE (Base) with 167000 km listed for AED 49000, and a 2010 SE Platinum (Mid++) with 97100 km listed for AED 62000. Considering the lower trim and average condition of the target car, I adjusted the price downwards from these higher trim models.
