Hello to all the members of the forum

I hope you guys could help me out. This is the first time that I'll be getting a car and I have 300k budget for a second hand at ito ang pinagpipilian ko Altis, Vios Or Mazda 3.

Questions ko guys are as follows:

1. Fit ba ang 300k budget for a good second hand Mazda 3 (this is my top choice)

2. Ano ang lamang ng bawat isa sa kanila (Im a total car newbie)

3. How much should I set aside for the paper works? Deed Of Sale, Registration, Change of Ownership etc.

I'll be getting one next week so please help me out.

Thanks guys and more power!
