To estimate the price of the 2019 RAM 1500 V8 5.7L Big Horn (Regular Cab) (Base), I first looked at the selling price of a similar car: a 2018 RAM 1500 Long Horn V8 5.7L Rebel (Double Cab) (Mid+) with 60000 km sold for SAR 125000 on 2024-01-06. Given that the car in question is a year newer and has slightly lower mileage, it should be valued higher. However, the Big Horn trim is a base variant, which typically sells for less than the Rebel trim. Next, I considered the listed prices of similar cars. The closest match is a 2019 RAM 1500 V8 5.7L Big Horn (Regular Cab) (Base) with the same mileage listed for SAR 82000. This listing is a strong indicator of the market price. Other listings, such as a 2019 RAM 1500 V6 3.6L Big Horn (Regular Cab) (Base) with higher mileage listed for SAR 72000, and a 2021 RAM 1500 V8 5.7L HEMI Limited (Top+) with lower mileage listed for SAR 178500, provide additional context. Considering the condition, mileage, and trim, I estimate the market price to be slightly lower than the listed price of SAR 82000, as listings are often higher than actual selling prices.
