well i was in the exact same position two months back and now own a ritz coincidentally my cousin bought a brio a month back.Having experienced both the cars i will give my opinion
*brio is an unconventional car it is the smallest in its segment and has been designed keeping cost in mind by honda this has resulted in some compromises such as glass rear hatch to save cost, asymmetrical and cheap looking dash , lack of bootspace , less space(compared to ritz), uncomfortable front seats....... so it somehow felt overpriced for what it offers
* both k12 and ivtec are comparable.K12 lacks low end grunt in the city but again this is a problem with brio too.
*ARAI mileage of brio is 18.4 and ritz is 18.5........so same again .At first i thought that brio will give better mileage than ritz........but my ritz gives 14.5 in city with AC on continuously.And i know for sure that brio doesnt give any more than that ( according to my cousin )
So they r evenly matched.But if you dig further these r the differences-
why ritz is better?
1 more space for passengers and in boot
2 better front seats
3 easy ingress/egress due to tall design
4 much bigger ( almost seems half a segment above brio )
5 conventional hatch and boot
6 cheaper accesories for fitment
7 more number of dealers in your city so u can find the best one for service
8 very good Ground clearance compared to brio
9 Ritz feels better built than brio ( sheet metal /sturdiness vise )
Why brio is better than ritz
1 a little more refined ( honda petrol is the best in this )
2 smaller turning radius than ritz
3 lighter controls especially steering
4 Honda brand ( i own a car from this brand and respect this brand a lot )
5 U will find less crowd in service centres during services( details huh
6 much better visibility all around
7 less prone to rattles ( i have heard this problem in marutis )
8 no ankle pain due to higher set peddles as in ritz
Cant seem to remember any more....
how is honda ass an maintenance ?
Excellent but expensive than maruti ( i know because i own both brands ).Regarding ASS
both brands r comparable.
One more thing i would like to add.... i chose ritz over brio even though i didnt need the space/boot space at all? somehow it felt more VFM
Also i would suggest u to take long test drives of both these cars and see which you personally find better to drive and seems more comfortable to you.decision making will become much easier and u will come to know which car suits you better
