How long have you been looking and what's your search radius? It took me a few months and the car was 3 hrs away. IMO it's better to figure out exactly what colors/options/price you have to have then wait/be willing to travel for the right car.
I wouldn't buy the Carmax car TBH. I would try to find a private seller with the car still under warranty. My fully optioned 08 24k miles 6 speed black/black no accidents etc I paid $27k last year. Hope that helps.
