advice for buying a used car

[jfresh]

i am thinking of buying a used car for the first time. i'm open for any advice for buying from a) a private seller (found on autotrader.com) or b) a dealership

maybe these questions are dumb but:
for a) do i still have to pay some sort of tax? i mean i know that from a dealership the price usually doesn't include tax, title, registration, etc.

is everyone (dealerships and private sellers) usually open to negotiation in price? i mean i know i could just ask but just generally is everyone always haggling?

besides car fax is there anything else i need to do before purchasing a used car?

again i apologize for the dumbness of these questions.

[NT!]

yes you have to pay taxes, you will most likely pay when you register the vehicle in your name.

yes, everyone haggles, some people more than others. often when buying a used car you have to be willing to walk away and come back another time if the person is not budging.

take the car to a mechanic you know and trust, have them give it a once-over.

locking this thread now since there are like five used car threads in OOT
