FIRST TIME CAR BUYER! WANT YARIS! HAVE QUESTIONS!!

[jBABEE91]

I've been researching about cars ALOT, and always end with a yaris. i have so many question so i hope you can help me.

i am 19, in college, and very independent.. i know im too young to want to buy a car on my own but my parents never was there for me (financially wise) and i had always work for everything i own. im an only child and the rest of my family is in another country... so there you go.. VERY INEXPERIENCE WITH NOONE TO HELP.

BUT MY CREDIT SCORE IS 709(= goood enough..

i want a 2 or 4 door white 2009 yaris hatch back and i'm thinking about getting it from this one dealership and this is the info from it..

2009 Toyota Yaris
Internet Price
$12,411
Series 5dr HB Auto
Transmission Automatic
Mileage 34216

i tried to "bargain" by researching other cars similar with lower price, and lower miles and telling him but the guy said the internet price is the lowest he can go and i may get 2.9 interest rate for 60 months and i have 100000 mile warranty. IS THAT GOOOD?

ALSO i am mostly likely going to the dealership on my own.. what do i need to know? cause I KNOW THESE PEOPLE will most likely add extra charges (like extra stuff) i don't need and i don't want that. And the contracts?? ANYTHING that will help me.

i'm inexperience and would like to learn from car owners..
