i was almost at same position as yours around 3 years back...
got wagonR for family, it is nice car with some pros and cons, here are from my side
PRO
1000cc life time token
engine is very responsive, fun to drive
buying new, will be peace of mind for atleast 3-4 years
have a good presence in market (better resale)
CONS
odd shape (but you will get used to of it)
paint quality is poor (imo)
logo will fade out after some time
in summer at peak time ac is just for front seats (as per my exp. on a short trip)
and the biggest con to me, after my recent visit to pak was it is manual
havent drive v2 but in general i can say its ac would be better than wagonR, being 1300cc it would be more powerful as compare to wagonR, heard its suspension is better than honda city, its shape is nicer than wagonR, i might be wrong on this one, it do have airbags.
and now lets say cons of it, being the best car for (imo) value for money still not popular as wagonR (less market presence - lesser resale), 1300cc every year car token-tax, running cost might be high as compare to wagonR
as pistonhead said and i will also highly recommend you to go for auto car mira/passo depending on your budget, you can follow visit some importers to guide you or help you, do look for mycar.pk they are good. but yeah good JDM will be expensive as compared to PKDM.
also there are rumors of suzuki announcing celario in auto, may be wait for it (if you can, or if you cant go for wagon-R) best of luck
