To estimate the price of the 2018 Audi A3 1.0L 30 TFSI (Base), I first considered the accepted offer of AED 38000 for a similar car with almost identical mileage and condition. This is a strong indicator of the market value. Next, I looked at the selling prices of older 2016 models with similar variants, which were around AED 31000. Given the age difference, the 2018 model should be valued higher. The listed price of AED 40000 for a similar 2018 model also supports this range, though listed prices tend to be slightly higher than actual selling prices. Considering these factors, the market price estimate is slightly above the accepted offer but below the listed price.
