To estimate the price of the 2016 Volkswagen Tiguan I4 2.0L Turbocharged SEL (Mid) with 121000 km mileage, I considered several data points. First, the selling price of a 2014 Volkswagen Tiguan I4 2.0L R-Line (Top) with 246900 km was SAR 28000, sold in September 2023. This car is older and has higher mileage but is a higher trim. Next, I looked at listed prices of similar cars. A 2016 Tiguan SEL (Mid) with the same mileage was listed for SAR 50000, but this is likely an overestimate. A 2015 Tiguan SEL (Mid) with 117800 km was listed for SAR 33500, and a 2016 Tiguan R-Line (Top) with 113850 km was listed for SAR 53000. Considering the condition and mileage of the target car, and adjusting for the fact that listed prices are generally higher than selling prices, I estimate the market price to be around SAR 35000.
