Yes there's a place for cabin air filter in BRV, you have to cut it with sharp knife cutter on front plastic face of that area similar in WagonR. Honda city cabin filter easily fit but you need to cover masking tape on filter area after insert cabin filter. i done in mine and its works perfect.
Main issue of Glory CVT transmission is company using low quality CVT fluid, a dealer says they replace CVT fluid with Liqui Moly Top tec 1400 & problem solved.
I don't think company will give a good after sale service on many other little issues which will maybe discover after certain period of time.
