wait for the new saga facelift and see first
but if insist on persona here are a few things for a quick rundown both good and bad
1. not fuel saving due to heavy car but some would say thats a good thing cuz planted
2. cvt jerk not everyone can accept even after all the tuning from each facelift
3. but this model year interior quite good looking got armrest p2 competing car this price dont have. and i like the aircond dials. rear view mirror got usb for easy dashcam somemore.
4. dashboard squeak and rattle down the road
5. and check for the radiator cuz alot owners report rust which result in overheat
6. check if maintain service with proton bc if not cannot claim free power window failure
other than that, 6 airbags, isofix, folding mirror, auto headlight, ok la this car. but i'd wait see new saga macam mana first.
i reckon the new saga price will touch above 50k judging the specs and upgrade by the leaks, also from the leaks the body looks the same, so probably interior space will pretty much the same with current saga right.
loading carseat or stuff is probably easier on the persona considering the size differecens.
But you're not wrong too for waiting the upcoming saga though.
