To estimate the price of the 2019 Volvo S90 2.0L T5 Momentum FWD with 53778 km, I considered several data points. First, a 2020 Volvo S90 T5 Momentum (Base+) with 77900 km sold for AED 108000 on 2023-12-01. Given the higher mileage and newer model year, this car's price suggests a slightly lower value for the 2019 model. Second, a 2019 Volvo S90 T6 R Design AWD with 66990 km sold for AED 84991.5 on 2024-05-16, and a 2019 Volvo S90 2.0L INSCRIPTION with 79657 km sold for AED 82441.5 on 2024-07-08. These prices are for higher trims, indicating a lower value for the base model. Third, the listed price for a similar 2019 Volvo S90 2.0L T5 Momentum FWD with the same mileage is AED 89990, but listed prices are generally higher than selling prices. Considering these factors, the estimated market price for the car in question is derived by averaging the selling prices and adjusting for the base trim and mileage.
