I'm looking into buying a 2nd hand car worth around 300k-350k and considering taking a loan from a bank or private lender to cover the balance after I pay 20%-30% downpayment. The problem is that I absolutely have no idea about this kind of transaction. Madali sana kung cash kasi kaliwaan lang kaso malamang hindi. So I have a few questions that I will very much appreciate if somebody can shed some light to:

a. what's the best place to get a loan?
b. what do i need to prepare? when do I need it?
c. would there be additional expenses except for the DP?
d. what's the participation of the seller
e. dealer vs private seller?

Salamat!
