To estimate the price of the 2018 Honda Civic I4 2.0L RS (Mid) with 185,000 km mileage, I first considered the selling prices of similar cars. The closest match is a 2018 Honda Civic I4 1.5L RS (Mid) with 143,000 km sold for 52,000 SAR in November 2023. Another relevant data point is a 2018 Honda Civic I4 1.6L LX Sport (Base) with 133,000 km sold for 37,000 SAR in August 2024. The 2019 Honda Civic I4 1.6L RS (Mid) with 52,000 km sold for 55,000 SAR in September 2024. The 2018 model with a 1.6L engine listed for 35,000 SAR with 173,000 km is also considered. Given the higher mileage of the target car and its 2.0L engine, I adjusted the price downward from the 1.5L RS (Mid) selling price of 52,000 SAR. Considering the depreciation and mileage, I estimated the market price to be slightly lower than the 1.5L variant due to higher mileage and market trends.
