The only data point available is a listed price for a similar 2020 Mercedes S320 I4 2.0L Turbo, Standard variant with similar mileage of 67600 km, listed for AED 215,000. Since this is a listed price, it is likely higher than the actual market value. Typically, cars sell for 5-10% less than their listed price. Therefore, I estimate the market price to be around 5-10% lower than AED 215,000, which would be approximately AED 193,500 to AED 204,250. I will take the midpoint of this range for a balanced estimate.
