Hey there, TS. Before I got my car, I was considering between Persona B-line with Saga FLX SE as well. But I decided to drive manual as I still like gear shifting, I took Persona instead.
Here is my comment :
Saga:
Nicer exterior design, I must admit the FLX SE design is nice. Those aunty won't think that you're driving 1.3 saga because this is FLX SE.
Rear passenger seats nicer than Persona's (personally sat on friend's saga before)
FC - With the CVT gearbox & lighter body, definitely will be better than Persona's FC.
Persona :
Spacious driver & front passenger seats.
Stable at high speed & even cornerning thanks to the rear multilink suspension.
FC - my Persona is 8L/100km based on the meter in my car. Which is quite good I guess as I travel in 50% city & 50% highway
As for the exterior, Persona B-line looks good after changing rims & some modification.
In the end, the final decision will be on your hand. Test drive both cars & decide in term of what's your need.
Cheers

FLX SE ada manual ke? I ingat CVT gearbox je! But nvm, happy with my Persona now
Driven it for almost a month. Love it

What he said not really true. Mine is at 15-16 cent/km.
