I got my Camaro with 32,000 miles for $10,872. (Yeah, it was my first car, so I remembered haha) Fortunate for me, my grandparents bought me my car for my Christmas present. But there are some pretty good deals if you go look on AutoTrader.com. I did a search on Camaros on there and found some great buys. I picked out a Z28 but they sold it the week before I told them I would come to look at it and, hopefully, buy it. :( So I found my car in Evansville, Indiana at Kenny Kent Chevrolet (VERY nice people, btw!)
Shop around at cars.com, autotrader.com, etc. You can find all sorts of good buys if you don't mind driving a little ways to look and buy!
Good luck!
