Finally manage to see and touch the physical of the car. Saw one at setia alam tesco, which executive white.
I was high hope on this car but sadly it turned out the other way around. Comparing to waja interior, I felt waja is much better in term of the material choice and fitting. The preve is just bit plastic to me, and the door panel also feel it. The speedo meter surprisingly is small, waja much better looking. The idea design is good is just the things arrange is not well balance and sleek enough. For the executive,  the setting is just too toyish feeling. The stering is small but doesn't have the waja feel more confirm and steady.
Engine bay doesn't looks neat enough if compare again with waja. The bay seems a bit large, maybe some space for turbo parts.
Lastly come to the my worst part of the car, is the rear seat. I thought it could be a flat rear seat, but there is the wheel base which make the seat not flat. If seating for 3 person, the both left right person which need to seat inside cause can't lay down the back bcoz the wheel base, the 3rd person will be cramp. The car is long enough for comfortable interior seating. Maybe they sacrifice for the front site. The seat also a bit low.
If compare to persona, yes it is better. But for waja, I think the waja interior is much better.
Only thing is the car exterior design itself. I am looking more on to the engine and the car design. Those extra feature is nothing special it had been in the market, all u need is juz include it. As for engine, it will depends on prt itself and also the car design.
A preve body with waja interior feel would be great.
