Well you said that you already have set a price limit. So I'm not going to get involved in what price range you should stay in. However, I have always read that you should never have a car payment any higher than 10% of your take home pay. So if you net 2000 a month, then your payment should be no more than 200.
Anyway, you want to look for a vehicle that has NEVER been in an accident. You can purchase a cars history report on carfax.com for about $20. Second, make sure you don't overpay for the vehicle. Check the vehicles blue book value on kbb.com.
As an easy, general rule of thumb I would stay away from anything American, and if you don't want to spend a lot of money on expensive luxury fixes then I would stay away from luxury cars and European cars as well. That would leave you with Japanese or Korean cars.
I would stick with a sedan, some sedans are just as safe (and some even safer) than certain pickups or even SUVs. People have this misconception that big cars are safer than small cars. That isn't true.
I would HIGHLY reccomend a Toyota Camry, Honda Accord, or Toyota Corolla, or Honda Civic. They all get great gas milage, are cheap and easy to fix, very reliable, and blend in with traffic (easy to avoid tickets and less vandalism/break ins)
tip number 1 - STICK TO YOUR BUDGET
tip number 2 - get an insurance quote BEFORE you buy the car, to see what your insurance premium will be
tip number 3 - be prepared to walk away from any car. if you show the salesman how excited you are about a car he will use that against you as leverage to pay more. if you act uninterested or like its not a big deal and explain that you don't need a car, you will be able to get a better deal and play hard to get
hope this helps a little. if you have any other questions don't hesitate to email me = )
