I analyzed the selling prices of similar cars first. The most relevant data point is the 2021 Nissan Xterra Titanium I4 2.5L with 60600 km, sold for 80500 AED on 2024-09-02, as it closely matches the car in question in terms of variant and condition. Another relevant sale is the 2021 Xterra 2.5L I4 with 39520 km, sold for 86000 AED on 2024-02-03, but it had lower mileage and average condition. The 2021 Xterra with 36500 km and good condition sold for 105000 AED on 2023-04-23, but its lower mileage likely increased its value. The 2021 Xterra with 74000 km sold for 95000 AED on 2023-07-25, but the condition was unspecified. Considering the car in question has 63500 km and is in good condition, its value should be slightly higher than the 80500 AED sale but lower than the 86000 AED sale due to higher mileage. Offers accepted by sellers, such as 83000 AED for a similar variant with 38000 km, suggest a market range. Therefore, I estimate the market price to be slightly above 80500 AED, considering the condition and mileage.
