If you're deciding b/w Civic Hybrid and Axio then go for Axio with closed eyes!
Hybrid Civic is the slowest 1.3L car, and economy wise It isn't great too. No one would be able to maintain It.
Maintenence wise, It would be easy for you to maintain Axio while the Civic would be difficult and you'll find no mechanics for It too!
Economy wise, Though Civic being a hybrid, Axio would have better economy both in City and Highways.
Parts wise, Finding parts would be difficult for both but for Axio It would be comparatively easy!
Now let's see towards other cars in your budget!
1) City 2013. You can go for City 2013, It would be much easy to maintain and would have the best economy.
2) Suzuki Swift 2014 (Brand new)
3) Honda Civic Reborn 2007-2009, though It wouldn't be good on pocket economy wise.
4) Honda Airwave.
I'll suggest you to go for City 2013 or Swift. I'll not go for JDM's since most of them are with tempered meters and fake auction sheets and usually are minor/major accidented and repaired by Pakistani so called "Ustaad's". While the City 2013 would be almost new vehicle and the Swift would be a brand new vehicle, now b/w City and Swift I'll suggest you to go for City since It has many pro's over Swift and no such con's.
