Which generation of Volkswagen Polo is the most reliable?

I am looking to purchase a reliable car for my daily commute and I have heard good things about the Volkswagen Polo. However, I am not sure which generation to choose from. Can anyone give me some insight on which generation is the most reliable?

In my experience, the 5th generation Polo has been the most reliable. The build quality and engine performance are top-notch.

I have had a great experience with the 4th generation Polo. It may not have all the latest features, but it has never given me any trouble.

I would recommend the newest 6th generation Polo. It has the most advanced technology and safety features.
