Believe me I was just passing by, thought to give a comment after reading the comments.
The Suzuki list of my garage is Khyber(1999), Mehran (2014), Swift (2015) cultus (2007), cultus (2017).
iwill try to be on point.
just want to tell my experience, that's why shared the Suzuki list.
SWIFT : better handling, better acceleration, better comfort. better space.
CULTUS : Airbags, Good mileage. new shape.
as I dnt know whats your priorities, if mileage isn't issue, go for swift anyday.
every car resale value is lower then anyones expectation, Put any car for sale on actual price, No one will come to buy, Reduce some lacs, everyone will come to take. (this phrase has different aspects)
Negative points:
Swift: 1328 cc, mean you have to pay token tax of 1500cc car, low fuel average/bad average
Cultus: Better options in this money, Like Swift 
In my view, and till Now the Suzuki vehicles ive used, ithink Swift is the best Product of Suzuki.
All are my words, Not implement on any body, and these are just suggestions
Peace
