For your height and fuel comsumption requirements look at an 03-06 Corolla Levin. 1.8 auto and the Levin has a sporty look with body kit, alloys etc. Still quite economical and should easily achieve your fuel economy requirements of around the 9l per 100km. I used to be able to achieve high 7's into low 8's per 100km with ease in my Sportivo with the odd lift engagement.
