@ Sid_Cruiser , Honda usually stick to the schedule but due to Heavy booking of Amaze and Limited Production capability in their current plant , some Brio variants have been slow or halted , but since you have booked SMT i don't think you will have any issues .
Regarding Brio ARAI mileage , Even i found 19.4Kmpl claims and also 18.4KMPL , so when i asked an executive at Honda about it , he showed me a Brochure which showed that VMT models due to additional weight of ABS and Air bags losses some FE figure and 19.4Kmpl is for mid (SMT and ExMT ) Variant , I had brought that Brochure home , if i find it i will scan it and put it up here
Brio is best VFM Petrol Hatch in its segment, i had checked Ritz and Swift and found them expensive and nothing more to offer , Wagon R is Good car but it is a 3 cylinder engine but you pay price for 4 cylinder Petrol hatch that's Suzuki's loot .
Micra is Good car but unreliable Service support from Nissan , Hyundai I10 is most overrated car in India , 1.2 Kappa variant costed a bomb then but now it has been withdrawn but i liked Grand i10 , and old Irde 2 1.1 engine in I10 is too old and Brio is a bigger car compared to it .
