If you are not limited to 1000cc Swift GL CVT is a wiser choice adding 200k to Cultus AGS.
The head unit is so/so. Does the job.
Had AGS Alto, its wiser to put the car in N on signals to save the clutch from extra wear and tear. But not mandatory in stop and go. Sometimes the car make clutch press and release motion so you your self would want to put it in N.
You can keep a slim wallet and a cell phone in front the compartment avaliable in front of gear under AC controls.
A normal size cell phone fits in the pocket avaliable on the driver side aswell.
Front cup holders are normal size.
I have a manual cultus does 13 to 15 kmpl in karachi drive. AGS Should do Slightly better.
