Car purchase Mazda3 G120 vs. 165

Hello dear members, I have a question because you don’t find so much about it. Play with the thought of buying a Mazda 3 (kodo design) needed and would like to know if the G120 or the G165 is running more than daily car. Although I drive more than 30,000km a year I still want to drive a gasoline truck that is no problem for me. I only found a forum where it was discussed so far and there was too much opinion. To the info I drive hardly any city more country roads with much 100s and 1-2 times a week also highway. Is the G165 or the G120 better suited for me? Thanks for your answers
