Airwave is junk, default tires also only size 14. I've driven it and it was a terrible feeling, also with respect to suspension.
As for the panoramic rooftop - lolz! Who wants sun in Pakistan, just tell me? We use the SR packages not for sun but for fresh air. Airwaves' panoramic sunroof is fixed and just for view/light, no air. Will turn the car hot in summer and allow extra entry facilitation for the bad guys.
Fielder all the way, very smooth drive, pick-up better than Altis 1600 MANUAL! I tested it yesterday.
Regards.
