Bhai buss kar dein... Let the Vios come, then we all will see which is more reliable!
Well... Its my personal opinion that in the same league, Honda engines are more robust and provide instant torque and acceleration, while Toyota engines are a bit sluggish (may be, Toyota vehicles are comparatively bulky and heavy when compared to Honda, power to weight ratio is more in Honda), but when it comes to reliability, nothing beats Toyota worldwide!
