Budget car for a big family but a luxurious to 5 member

I own versa DX by April 2007, as a regular user of maruti vehicles I never feel about service.

But the seating arrangement is not sufficient, if it is for domestic purpose then goto 5seater & extend baby seats at rear. It may solve legroom problem, as original version do not have adequate space like omin 5seater with extended seats.

Another problem I am facing is vizziling noise from rever view mirror, not able to solve.

Other wise it is good family vehicle
