You are right about the backseat seating space, plus it has flatter floor at the back, which is comfortable for middle seat passenger. The other thing which is very simple, but i really like is the opening of doors till 90 degrees, In cultus, alto, doors hardly open 60 degree angle, that makez it very difficult for old people and luggage to get in and out.
In dash player is good overall but not for those who wants LCD. Other thing wrong with in-dash player is the Clock, it has good display area but time does not persistent when car is switched off, this must be something to do with electrical stuff that people at Pak suzuki got wrong, they should figure it out by now and get it set for all customers.
Good luck for your purchase!
