The car to be estimated is a 2018 Lexus IS350 V6 3.5L F-Sport (Top+) with low mileage of 12,500 km. The closest data points are two 2016 Lexus IS350 V6 3.5L cars, both with much higher mileage and older by two years. The first 2016 car, an Elite (Mid) variant, sold for 62,500 SAR with 247,800 km. The second 2016 car, an F-Sport (Top+) variant, sold for 68,000 SAR with 236,470 km. The 2018 model is newer and has significantly lower mileage, which increases its value. Considering the depreciation and the premium for the F-Sport (Top+) variant, the 2018 model should be valued higher than the 2016 F-Sport (Top+) that sold for 68,000 SAR. Given the low mileage and newer model year, a reasonable estimate would be significantly higher, accounting for the better condition and newer year.
