I think your budget will fit for an LXI or even VTI model. Sa buy and sell kasi, medyo mataas ang price, but you can check them out to get some ideas. You may also try a Toyota Corolla but if you really want a Civic, get the VTI.
It's better if you will buy the car from someone you know. Just a piece of advice, don't rush sa pagbili para makapamili ka ng mas maganda o kaya mas mura.
