On the verge of buying a car

...and I feel nervous. I have dealt strictly on the internet with several dealers. I have done my homework and fought for $14,995 for the price of the car I want. 2 dealers will offer it at that price. One is the dealer we bought my mom's car at and I like. I am just worried/nervous they'll add hidden fees. The car should come out to $16,500 after tax and license. To have it cost more would put it out of my range. I'm worried we're going to have to fight and they'll try to pull something on me. I'm sticking firmly though to my decision- give it to me at this price or else. I've waited months already and can wait longer.
