To estimate the price of the 2012 Volkswagen Touareg V6 3.6L Comfortline (Mid) with 218000 km mileage, I first looked at the selling prices of similar cars. A 2014 model with 238700 km sold for 35000 SAR, a 2014 model with 323000 km sold for 34500 SAR, and a 2013 model with 198000 km sold for 35000 SAR. These prices suggest a range of 34500-35000 SAR for slightly newer models with higher or similar mileage. Next, I considered the listed prices of similar cars. A 2012 model with the same specs and mileage is listed for 31000 SAR, while another 2012 model with 204000 km is listed for 36000 SAR. Given that listed prices are generally higher than selling prices, the actual market value is likely lower. Considering the car's age, mileage, and condition, I estimate the market price to be slightly lower than the average selling prices of newer models but higher than the lowest listed price.
