I drive serena... and I think it is pretty good to fit your family. I try sitting at the 3rd row, and it is comfortable, enough leg space and height, I fell asleep on the trip sitting on the 3rd row. By the way serena is an 8 seater MPV2+3+3. But it is slightly over your budget of RM125k though

Hmm... true, if compare to alphard, it is less. But alphard unless you get an old recond, else it will not match budget
compare to Proton Exora, it is less as well, price lo, 40k different
compare to Innova, well... just say there is much who thinks Toyota is the best.

Anyway... know your budget and know your needs, what you want to use the car for and can it fulfill them
It will be a simple decision once this 2 is clear
