To estimate the price of the 2017 Hyundai Elantra V4 2.0L Smart (Base) with average condition, I first considered the selling prices of similar cars. A 2018 Elantra with the same variant and slightly higher mileage sold for 38500 SAR recently, which is a good reference point. A 2016 Elantra with a different variant but similar engine and condition sold for 35500 SAR. Considering the 2017 model year and average condition, the price should be slightly lower than the 2018 model but higher than the 2016 model. The listed prices for 2017 models with a 1.6L engine were 39500 SAR and 38000 SAR, but these are for a smaller engine and higher mileage, suggesting a slightly lower market value for the 2.0L engine. Taking all these factors into account, I estimated the price for the 2017 Elantra 2.0L Smart (Base) in average condition.
