Take as long as you can before getting one and find one with the parts that you would want to have on the car like the type of rims, engine size, color of interior, 4or5 lug, with original bumpers, inspected and smog legal if its an issue where you are from. If you don't, you will be spending more than perhaps expected.
I promis, once you get one, the one you really wanted will come out of nowhere! Many have gone by for me.
