Brother I am not misguiding or confusing you.
I made the exact mistake 2 years ago:
Bought the 2007 Altis for 2 months and than replaced it with the 2008 September GLi with 4,000 KM on odo.
The car is big and seriously lacks power if you have ever driven an Altis.
GLi on petrol was even slower than the auto Altis on CNG in normal "D" mode.
I rectified the mistake and bought a 2007 Axio 1.5L and now very happy and satisfied.
