To estimate the price of the 2012 Chevrolet Malibu V6 3.6L Turbo LS (Base) in bad condition with 270,000 km mileage, I considered the following data points: 1. A 2011 Chevrolet Malibu V6 3.6L Turbocharged, average condition, 193,000 km, sold for 10,500 SAR on 2023-12-04 and 2023-12-15. 2. A 2013 Chevrolet Malibu V6 3.6L, average condition, 169,000 km, sold for 17,500 SAR on 2024-06-09 and 2024-06-10. 3. A 2013 Chevrolet Malibu V6 3.0L, average condition, 310,000 km, sold for 14,000 SAR on 2024-03-30. 4. A 2013 Chevrolet Malibu V6 3.0L, good condition, 151,000 km, sold for 25,000 SAR on 2024-02-05. Given the car's bad condition and higher mileage, I adjusted the price downwards from the average selling prices of similar cars in better condition and with lower mileage.
