To estimate the price of the 2021 Honda HR-V 1.8L EX DX (Base) with 126739 km mileage, I first considered the selling price of a similar car: a 2021 Honda HR-V 1.8L LX with 98546 km sold for AED 55241.5 on 2024-10-05. This car has lower mileage and is a different variant, so the price for the target car should be slightly lower due to higher mileage and being a base variant. Next, I looked at an offer accepted for a 2021 Honda HR-V I4 1.8L EX (Top) with 110000 km for AED 51000 on 2024-07-15. This car is a higher variant but with lower mileage, suggesting the target car should be priced lower. Finally, I reviewed listed prices for similar base variant cars with mileage ranging from 80060 to 124822 km, with prices between AED 59500 and AED 67990. Given the target car's higher mileage, its price should be on the lower end of this range. Considering all data points, I estimate the market price to be slightly below the lowest listed price due to the higher mileage and average condition.
