Are these good cars? Just want an opinion on them?

I have been saving up for a used car and found these 3 cars.

Here, this will be more helpful than a yes / no answer -10 things to look for when buying a used car: https://blog.allstate.com/10-things-to-look-for-when-buying-a-used-car/

There are a lot of things to consider when buying a used car and most of them require seeing the actual car!
One place to start is looking at cost of ownership figures! Some cars are dependable but have high insurance rates (such as a Honda Civic because it is stolen so often).
Some cars have low insurance rates but a higher frequency of repair (like the Chevrolet), but the parts are plentiful and most mechanics can work on them.
Some cars only have the name going for them, such as the VW. Which is not dependable and recently achieved fame for emissions violations.
Factually I would not consider any of the three!
While the Honda might be the best one of the group, I would still prefer a Mazda or a Ford. Both of which tend to be dependable and have lower frequency of repairs while being less expensive to insure.

No

I would get the Passat if I could afford it.

Which one is in the best condition as determined by your mechanic?
