Sir Civic is simply a better car if you have no issues with resale or parts or rough roads or dashboard design etc etc which are the Corolla's only selling point.
Cruise Control is a very good feature if you travel frequently on highways and could be decisive but the PROSMATEC shift is much much better, even the 01 PROSMATEC has a smoother shift then a 0 meter Altis.
Corolla's engine is a gem so is the braking but the chassis and body control do not support them at all.
Corolla is quieter at High speeds but stability and road holding is no where near Civic.
Petrol tank and trunk of Corolla is bigger, and they are giving factory leather seats, if that matters.
Go for |Civic, they are now giving a DVD navigation with rear camera and some nice colors too.
Add some HIDs, good premium tires and hand stitched leather seats and you will be good to go for next couple of years.
There is no point in experimenting just for the sake of experiment.
