go for stream i will say, coz it a new model. toyota wish already have for the past few years. for course, wish is 2.0cc. stream is 1.8cc so u cannot compare lor. if u have lower budget then go for recond 1.8cc wish lor. btw, if u wan more power might go for mitsubishi grandis 2.4cc.
but i will say this type of car is not about performance lar, if wan performance go for caldina then.
try to consider mitsubishi grandis 2.4. it is the car of the year 2008. far better than wish and stream.
