First, I considered the selling price of a 2013 Lexus IS300 3.0L V6 Platinum with 271500 km mileage, which sold for AED 25000 on 2024-04-02. Given that the car in question is a 2011 model with 219585 km mileage and in bad condition, I adjusted the price downwards. Next, I looked at an offer accepted for a 2011 Lexus IS300 3.0L V6 Premium with 169000 km mileage at AED 28000 on 2023-09-13. Since the car in question is a Platinum variant but in worse condition and higher mileage, I adjusted the price downwards. Lastly, I reviewed the listed prices of similar 2013 models, which ranged from AED 26500 to AED 36000. Considering the car's bad condition and higher mileage, I estimated a lower price.
