To estimate the price of the 2013 Audi A5 TFSI Quattro S-Line I4 2.0L Turbocharged 40 TFSI Design, I first considered the selling prices of similar cars. A 2013 Audi A5 S-Line Quattro with similar specs and a slightly lower mileage sold for SAR 35,000 in December 2023. Another 2013 Audi A5 Sportback with a smaller engine sold for SAR 32,500 in June 2023. A 2011 model with similar specs but higher mileage sold for SAR 16,000 in September 2023. The listed prices for similar cars range from SAR 27,500 to SAR 42,000, but these are generally higher than actual selling prices. Considering the car's average condition and higher mileage, I estimate the market price to be slightly lower than the SAR 35,000 selling price of the better-conditioned car.
