Para naman mabago. The platform and drivetrain of the Vios has not changed since the introduction of the 1st gen back in 2003. The City is much better than the Vios in terms of interior space, quality of materials and in the performance department. Also, so far I have not yet seen a City with a sagging rear like the Vios when loaded. But then again, ang dami na rin nito.
IMHO the Rio is a good alternative. I find it to be very upscale, not looking out of place even when parked beside Euro subcompacts. For 678k you already get driver's airbag, ABS, all power amenities and a 6 speed tranny. Considering that it has corrected pretty much all of the Accent's flaws and is better equipped than the base Accent M/T I find it a very good deal.
