The petrol Swift is a sluggish car,quite boring to drive in stock form. The diesel is much more fun any given day.
Also for those who think, Diesels are expensive to maintain, well the situation is quite different now with new age diesels. They are quiet, more efficient, require less maintenance etc..
I happen to have both, the petrol as well as diesel variants and I prefer the Diesel more. done 60k kms in 2.5Yrs and still going strong irrespective of the abuse I throw at it
OT :
This is similar for the Getz too
Diesel is too much fun compared to the petrol counterparts
