2-comfort is equally good if compared with old shape city
3-cornering is much better then old shape city
4-no space in the boot of swift (hatchback)
5-fuel economy: it has only done 100Km will check after 2 to 3 fuel tanks
6-driving pleasure is equally good.
7-pick is much better then city old shape
8-build quality seems good, but comparision for durability needs time.
9-plus points are: fog lamps, bridgstone tyres, alloy rims, ABS.
10-driving position is also equally good.
11-saving of 2.5 to 3 lac almost.
12-more token fee & registration fee due to 1328CC.
13-cabin noise is same as of old shape city.
