To estimate the price of the 2013 BMW 328 I4 2.0L Twin Power Turbo, I considered the following data points: 1) An offer accepted for a 2014 BMW 328 I4 2.0L Twin Power Turbo with 190,000 km mileage at SAR 43,000 on 2024-08-05. 2) Listed prices for similar 2014 models: one with 190,000 km at SAR 47,000 and another with 225,000 km at SAR 54,000. Given that the car in question is a 2013 model with 123,000 km, I adjusted the price downwards from the 2014 model prices due to the older model year but upwards due to the lower mileage. The accepted offer of SAR 43,000 for a 2014 model with higher mileage suggests a slightly lower value for the 2013 model. Considering these factors, I estimated the market price accordingly.
