To estimate the price of the 2011 Jaguar XF 3.0L V6 Portfolio (Top) in bad condition with 188000 km mileage, I considered several data points. First, a similar 2011 Jaguar XF 3.0L V6 Portfolio with 149500 km had an offer accepted at AED 18000 on 2024-04-03. This car was in better condition and had lower mileage. Second, a similar car with 149500 km was listed for AED 20000 but delisted on 2024-05-16, indicating it might not have sold at that price. Third, another 2011 Jaguar XF 3.0L V6 Portfolio with 140000 km was listed for AED 25500 but delisted on 2023-10-27. Given the bad condition and higher mileage of the target car, I adjusted the price downwards. Additionally, a 2012 Jaguar XF 3.0L V6 Portfolio with 196300 km was listed for AED 18500 but delisted on 2023-10-12. Considering the bad condition and higher mileage of the target car, I further adjusted the price downwards.
