You can get a 2005-06 in not so great condition here in Islamabad so maybe in Lahore you can get a Cultus in better nick...
The rear sticker on these cars usually tell their variants...
VXR - simple, non-efi
VXRi - simple, efi
VXL - options, non efi
VXLi - options, efi
All are 997 CC 3 cylinders... They started 4 cylinders too after some year but I am not sure when... Although you can open the bonnet to see how many cylinders...
I hope that clears some bits of it...
Cheers...
