I BOTH A WAGON R AND SANTRO XING . THE POINT IS WHAT U WANT? IF YOU WANT A GOOD AC THEN SANTRO IS BETTER BUT IN ALL OTHER TERMS SANTRO DOES NOT MATCH A WAGON R's PERFORMANCE ,I MEAN THE COMFORT OF DRIVING ( ESPECIALLY LONG DISTANCES) , FUEL ECONOMY , SERVICE AND TOP OF ALL IT's POWER STEERING WHICH I THINK IS THE BEST IN IT's CLASS . IN FACT I HAVE DRIVEN FEW MANY CARS LIKE HONDA CITY ETC BUT THE POWER STEERING OF WAGON R IS BETTER THAN THE HONDA's . BOOT SPACE WISE ALSO WAGON IR IS BETTER
