Take your mom, dad, brother or boyfriend with you and go look at used cars from a reputable dealer.
They will give you a warranty and all.
I do not know much about buying a car on the Internet,
I really believe you should do that in person.
If you have a good credit rating, you will have no trouble getting a loan.
Make sure you get a car with good safety features first and foremost.
And as far as I know, all cars have seat belts in the back seat.

The price of gasoline is not going down anytime soon.
Have you thought about where you will park the car, since you live in Manhattan?
Oh, and insurance is higher there also.
Please take all this into consideration before you make this decision.
Cars are high maintenance and they do not give Yorkie Kisses.
Good luck.
