What are the most important technical specifications to consider when buying an Audi?

I'm looking to purchase an Audi but I'm not sure which technical specifications are the most important to consider. Can anyone provide some guidance?

When considering an Audi, the first thing you should look at is the engine size. This will affect not only the performance of the vehicle, but also fuel efficiency. Additionally, take a look at the transmission type and whether it is manual or automatic to fit your driving preference.

Another important factor to consider is the Audi's safety features. Look for models with features such as blind spot monitoring, lane departure warning, and rearview camera to ensure a safe driving experience.
