Wasn't Suzuki Mehran Carby to Euro II a facelift?
The above example is what Pak-Suzuki considers facelifts.. 
I don't expect a proper "facelift" for Swift till the next decade or so.
Swift will face the same fate as It's siblings Mehroo, Cultus, Bolan, Liana, Ravi faced.
The day when we'll become unhappy with Swift and It's sales would drop,
PS would Instantly Introduce a facelift, but that would never happen.
Swift sold like anything at start and would continue too.
We're happy and so are they without "working hard"
