I have test driven both, and spark wins hands down for Indian city commute with small roads and tight u-turns
Palio matters because I was stunned by the driver comfort it offers. The pic shows driver seating positions. Even swift or the new Vista do not provide such comfot.
Take note at the Red arrows.
1 Bent knees tucked under the dash board
2 Heel not relaxed
3 no thigh support
So I concluded, Palio is the best for those who want driver comfort and have frequent long long driving. Instead of the low powered 1.1 Palio MJD will do more justice to the brilliant designed machine
I thank fiat for designing such a car and making it affordable even for the common man. Wonder, when the most reliable, best customer satisfaction Maruti will copy paste this design.
