get your fiance a test drive to the cars she wants. since she will be the one to drive, you are gonna need her inputs once she tried test driving the available cars.
Ask her which one she finds the easiest to drive and PARK. since first time drivers usually have a hard time parking cars.
From the test drive you can narrow down your choices.
Personally would pick the Toyota vios simply because of its safety features which is a much needed feature for your peace of mind.
the honda city will come in a close second. You could also check the Honda jazz/Toyota yaris or the mobilio. not sure if it will fit the budget thou.
