hey guys! haven't been on in quite a while. i've been getting my driving hours in

i need all the advice i can get. i started thinking about my first car, and thanks to dragoneye:p , i've been saving every penny i have to hopefully be able to get my hands on a camaro

i've been looking at a few but i would love to have some help from you camaro5 experts. i'm looking at used....idk about anyone on here but my parents have no intention on buying me a 58,000 range rover as a
first car

what would you guys say should be the cut off on mileage. i'm smart enough to know not to buy one with 250,000 miles on it for 10 grand but what do you guys think? i'd love to hear anything you guys think about buying used cars and such!
