I Also Bought new SWIFT atleast it is brand new. No tension for next 2 -3 years. 6000 Driven yet and believe me am getting 17-18 KMPL Speed 80 to 90Km on highway and 12-13 kmpl in cities. Don't trust on used cars because i bought VITZ 2008 44k on ODO Last year but after driving 7k more I felt many problems and than I sold it. JDM quality is best but if a honest dealer provide you the best car otherwise all are cheaters.
Go for brand new swift you will really enjoy
