Corolla 1.4 G6 purchasing advice/diseases etc?

Hello, I’m interested in a corolla and wanted to know what the problems like this have, etc. What does the 1.4 g6 have for typical problems? does the car like to rust? what is the 1.4 engine like? (that it’s not a racing car I already know:P) the 6speed transmission is the same as the 1.6 g6? otherwise something to consider when buying? spins the electric time? so the car should be eig only for the city. good as never autobahn.. I think that the 1.4 will be good for it or? I don’t know.
