i'm not sure about which is more fuel efficient between toyota 1.3 vs honda 1.5.. but i think a honda 1.3 is more fuel efficient than toyota 1.3. if you're (or your wife) is not into speeding, then better get the 1.3 nalang.. for me i can tell na ang 1.3 bitin or what. it depends on your personal preference. maybe para saken bitin ang 1.3 pero sayo ok na.. it is for you to choose which is which..
