To estimate the price of the 2017 Maserati Quattroporte V6 3.0L Twin Turbo (Base) with 41000 km mileage, I considered the following data points: 1. A 2017 Maserati Quattroporte GTS (Top) with 54000 km sold for SAR 120000 on 2024-07-22. This car is a higher trim and has more mileage, so the base model should be valued lower. 2. A 2015 Maserati Quattroporte V6 S (Mid) with 90500 km sold for SAR 94000 on 2023-09-18. This car is older and has more mileage, so the 2017 base model should be valued higher. 3. A 2015 Maserati Quattroporte GTS V8 3.8L Twin Turbo with 106620 km sold for SAR 97500 on 2024-03-10. This car is older and has significantly more mileage, so the 2017 base model should be valued higher. 4. A 2017 Maserati Quattroporte V6 (Base) with 41000 km is listed for SAR 155000 but not delisted, indicating it might be overpriced. 5.
