Brother a friendly advice for you. Take WagonR VXL with closed eyes. You will be more confused after reviews, suggestions, etc Its my personal experience. Get a New ride and drive with care and enjoy next 3-5 years with peace of mind.
15 Lakh budget pe jaogay to log kahaingay phir CITY hi kiyon (Hard suspension, Not much comfort, etc) phir 18 wali select krogay koi to espe tanqeeed...
15 lakh wali product 10 lakh wali se compare honi nai chaiye, u just think what you can get in 10 Lakh in local market... (Nothing)
a Crapy Cultus, FAW (Resale), etc
so Go and Get Wagon R as you already mentioned that SHape of wagonR is acceptable at your end.
