I have kept grande and currently driving a Altis 1.6 X, Grande takes the cake in driving pleasure and goodies along with better fuel economy (on highway, in city both return same figures).
Only positive point of 1.6 is hot cake resale and an easy to maintain & sturdy (but old school 4spd) transmission. (In grande changing transmission oil is whole project, there are many threads on PW)
Overall grande (even two years used) is more attractive package for me at least.
