To estimate the price of the 2012 BMW 730 Li 3.0L I6 Standard with 233300 km mileage, I considered the following data points: 1) A 2013 BMW 730 3.0L I6 with 55500 km sold for AED 38000 on 2023-09-27. Adjusting for higher mileage and older model year, the value decreases significantly. 2) A 2012 BMW 730 Li 3.0L I6 with 168500 km sold for AED 35000 on 2024-03-16. Given the higher mileage of the target car, the value should be lower. 3) A 2013 BMW 730 3.0L I6 TC with 208750 km sold for AED 20000 on 2024-07-15. This car has a similar mileage but is a year newer, suggesting a slightly higher value for the target car. 4) An offer of AED 21000 was accepted for a 2012 BMW 730 3.0TC I6 with 193800 km on 2023-11-21. 5) The target car is listed for AED 26000 but not delisted, indicating it might be overpriced.
