Ravibhat - I see no logic whatsoever by making SX4 as Swift and NHC as Santro and comparing, please. I have extensively driven Swift, Santro, NHC & SX4 and can very much say that a Swift handles much better then a Santro anyday, a NHC cant hold a candle to the SX4 as far as handling is concerned. The NHC has lower noise but Santro having less noise then a Swift
All this is off topic and the buyer has already finalised on his decision so no point talking about Santro and Swift here, please. Maybe your limited edition car was a lemon but Swift is much better then a Santro and hence 2 segments apart.
