I started by looking at the selling prices of similar cars. Two 2018 BMW X5 35i 3.0L I6 Twin Turbo M kit with similar mileage and condition sold for AED 87,000 each in July 2024. These cars are of the M Sport variant, which is typically more expensive than the standard 35i variant. Next, I considered the offers accepted by sellers. The offers ranged from AED 106,500 to AED 135,000, but these cars had lower mileage and were in better condition. The listed prices of similar cars ranged from AED 97,500 to AED 138,000, but these are generally higher than actual selling prices. Given the target car's average condition and higher mileage, I adjusted the estimate downwards from the M Sport selling prices and considered the lower end of the accepted offers and listed prices.
