I suggested to a friend to get a Mazda 3 hatchback for his University age son. He is looking at 2010 or 2011 model with Automatic Tranny.

What is the advantages/disadvantages for the 2.0 litre vs the 2.5 litre models?

Aside from more power and more gas consumption? Is one version more desirable than the other?
I am thinking along the lines of service, timing belt/chain? , durability?

Any input is appreciated.
