To estimate the price of the 2016 Audi R8 Plus V10 5.2L Quattro, I first considered the new car price for the 2025 Audi R8 V10 Coupe, which is AED 714000. Given the car is 8 years old, I applied a 10% annual depreciation, resulting in an approximate value of AED 297000. Next, I reviewed the listed prices of similar cars. The closest match is a 2016 Audi R8 with 39800 km listed for AED 420000. Other 2016 models with similar mileage are listed between AED 410000 and AED 420000. Considering the depreciation and the listed prices, I adjusted the estimate to reflect the market conditions and the car's good condition.
