alsvin is the entry level sedan, yaris is the next upgrade...
alsvin has some extra accesories that they count, like tpms, heated rear view mirrors, cruise etc. but in real life these hardly matter. It does not have the refinements that yaris will provide.
yaris has real features, traction control, hill start assist, vehicle stability control, smart entry, push start, three driving modes... further it has a much superior cabin, acoustic windscreen that makes it very peaceful, climate control is a treat vs the ancient ac alsvin provides, smart entry and push start give you a much premium feel, much much superior audio system, very superior seating, Alsvin's rear seat is a competition for cultus only while yaris has a beautiful rear seat. CVT is much much refined hardly hear the gear shift, sports mode and econo mode make driving a pleasure, moreover why i hated alsvin was fuel, Yaris is about 5 to 7 kilometers extra.
while leaving any evening party or get together, the LED back lamps of yaris leave a much superior impression of your car vs the stupid small rear lights of alsvin... matlab no road presence/impression
one last thing, if you are sitting somewhere and you have that Toyota FOB/key in your hand, you get another level of respect while with a chinese car's key in hand, you always feel belittled.
