Is Audi A4 a reliable and efficient car?

I am considering buying an Audi A4, but I am not sure about its reliability and efficiency. Can someone who owns this car give me some insights?

In my experience, Audi A4 is a highly reliable car. I have been driving mine for 5 years now and have not faced any major issues.

I would say that Audi A4 is quite efficient as well. It has a good fuel economy and performs well on long drives.

I have been disappointed with the reliability of my Audi A4. It has broken down several times and I have had to spend a lot on repairs.
