I want to buy Suzuki Alto JDM 660cc 2008-09 (old shape) model. I want to go for MANUAL transmission as I like manual + it has better fuel efficiency but its really hard to find a good condition 08-09 manual model.

If you guys or your friends own MANUAL and/or AUTO Alto JDM, do you guys know the fuel consumption difference?

What is the fuel consumption of MANUAL Alto 660cc 08-09 model with and without AC in city driving?

What is the fuel consumption of AUTOMATIC Alto 660cc with and without AC in city driving?
