To estimate the price of the 2019 Renault Koleos I4 2.5L PE 4WD (Base+), I considered several data points. First, I looked at the selling prices of similar cars. The closest match is a 2021 PE 4WD (Base+) with 38,000 km sold for AED 62,000 on 2023-11-13. Adjusting for the older model year and higher mileage, I estimate a lower value. Another relevant data point is a 2019 SE (Mid) with 103,561 km sold for AED 54,000 on 2024-05-23. Given that the SE is a higher trim, the Base+ should be valued slightly lower. The dealer sold a 2019 SE with 89,662 km for AED 50,995.75 on 2024-08-13, which also supports a lower estimate for the Base+. The listed prices for similar cars are AED 55,000 and AED 57,000, but these are typically higher than actual selling prices. Considering all these factors, I adjusted for the car's condition and mileage to arrive at the final estimate.
