To estimate the price of the 2015 Jeep Grand Cherokee V6 3.6L Overland (Mid++), I focused on the selling prices of similar cars. The closest match in terms of engine and condition is the 2015 Jeep Grand Cherokee V6 3.6L Limited (Mid) with 180000 km mileage, sold for 49000 SAR on 2024-06-30. Another relevant data point is the 2015 Jeep Grand Cherokee V6 3.6L Laredo (Base) with 196000 km mileage, sold for 40000 SAR on 2024-06-23. Considering the Overland trim is higher than the Limited and Laredo trims, I adjusted the price upwards. Additionally, the mileage of the target car is 178000 km, which is slightly lower than the Laredo but higher than the Limited. Given these factors, I estimated the price by averaging and adjusting for the higher trim level.
