Vitz in 2014 had a facelift (not a model change). That car is quite expensive as it just started coming into Pakistan this year and has higher taxes.
Vitz 2011/2012 is very good. I used it for a month or so and was giving me 16+ average in Islamabad city driving during winters (some AC to defog the screens). It does have higher engine sound (similar to the older versions) but you can certainly tweak/ lower it by trying different oil types and grades.
Overall good car. You should be able to get a good car 2011 / 2012 model within 12lacs range. If you go for "Smile Package" then its another 50k on top of it.
If you can increase your budget to 13.5 lacs, then you can get 2013 model fresh import but you will have to spend money on registration etc.
Good Luck
