The main changes between the two models (gen5/gen5.5) are ,headlights,tail lights, gauge cluster, I think the front bar may be slightly different as well and more misc trims ect. They are the same car but the 05 model has been face lifted and on the most part has a cleaner more attractive look about it because of these minor changes. The Sportivo you're looking at is one of the more sporty models of the Camry and has upgraded sport suspension (stiffer,strut bar ect), sports trim (seats) sports headlights ,body kit ect. The Azura is more of a luxury model (more expensive higher grade) that has leather trim,smoother suspension, sat nav,woodgrain interior, climate control (bonus has the same Sportivo body kit) ect. Both are really nice top of the line Camry's but it really depends on what you look for in a car to which you should buy. I like Azura's personally because it combines both sport and luxury in the same package and anything missing from a comparative Sportivo model can easily be transfered over to an Azura, but that's just me :)
