To estimate the price of the 2018 Toyota Yaris SE 1.5L I4 sedan, I focused on the selling prices of similar cars. The most relevant data points are the 2017 and 2019 Toyota Yaris SE 1.5L I4 sedans. A 2017 model with 105500 km sold for 30500 AED in September 2023, and a 2019 model with 102500 km sold for 42000 AED in September 2023. Considering the 2018 model year and its mileage of 51530 km, which is lower than both, it should be priced between these two. The 2017 model with similar condition and higher mileage sold for 30500 AED, while the 2019 model with better condition sold for 42000 AED. Given the 2018 model's lower mileage and average condition, I estimate its price to be slightly higher than the 2017 model but lower than the 2019 model, around 36000 AED.
