Let's put some light on your points..
1.Not as durable as City..
No doubt City is a Durable car, but Liana is not even a year old, how can anybody claim as such...
2.Liana has less resale value then City..
Suzuki has less resale then Honda... Lol.. you have got to be kidding.
3. City has good suspension as compared to City..
That's not true also.. the problem is the tyres Suzuki is putting on stock Liana... if one replaces it, it totally transforms the car, there is nothing wrong with the suspension.
I have Liana since August 2006, Not a single problem till now..
