1.It's good car and is comfortable and has good suspension as compared to its next model
2.Fuel average is best in 1.3 category where as swift is not much fuel efficient
3.Where as swift is sports and fast city is more of family car with comfortable drive (Swift suspension and seats are hard compared to city)
4. Car has good resale if properly maintained (talking about Islamabad a mint condition city 08 70-80k driven cost 11-11.5 lac
6.Manual is better in resale as compared to vario , as manual is cng friendly and vario doesn't support cng
7.It depend on your preference (Both are different categories cars)
8.i dont know about the price as i am in Islamabad and here cars prices are different from Karachi
I extra i would like to add if you are going for vario do check the gear box properly and many are not maintained and because of that the gear box need to be changed which is quite costly further more the vario transmission is cvt based which is new technology and is also introduced in new altis grande
I would further also advise you to think about city steeramatic which is 1500cc and it also has 7speed cvt transmission and also paddle shifter in which you can drive an automatic car like manual car and change gear manually from the buttons provided on steering
Also note this that i am saying this all on my personal experience as i own city 05(similar to city 08 except shape ) and i own a suzuki swift 12 too
thanks
