Yeah I bought my Stagea through AJM and they have a good selection of cars there.
But if you are going to come down to look, there are about 4 dealers in Slacks Creek area and about 4 or 5 dealers scattered along Logan Road, on the southside, (these are just guesses).
Whichever dealer you do go through, be prepared to pay more than a private car, but expect a warrantee.
Know what type of car, in what state and your price range and stick to it, and try to push dealers as far as they can go on the price.
Good Luck!
