A lot of responses from people wishing the prices were lower.
Try finding the prices quoted in this thread for MM, MB, AFM and CV, and most likely you will be unsuccessful and see the prices rise as you are searching. Who knows, maybe you get lucky, but most likely not.
For reference I sold my CV for $7,500 last April, and I have not seen any others for less than $7,000 since then. I know a dealer paid a local guy $5,000 for his CV, then turned around and put a price tag of $8,999 on it. So if dealers are willing to pay $5,000, how in the heck do you think you are going to buy one for $4,500 unless you get extremely lucky.
