@boomerang,
Pawn shops vary a LOT.
I'm pretty sure the rules vary from state to state too, so I will speak in generalities...
I rarely shop pawn shops, because I have dealt with them on the other side of the coin.
they buy, (really cheap) or own after default on payments, stuff from poor folks.
then resell it at a couple times what they have in it.
most are owned by people that I would not consider as socially responsible as you or I.
yes, great deals can be found. most of the merchandise (there are scoundrels) is in good shape, because they only buy or loan on good stuff) they pass on a lot of merchandise.
doubtful as to a test drive, but then again, each one is different in how the owner plies his trade.
I would ask around and find someone who has dealt with the pawnbrokers in your area.
bad news travels fast.
good luck...
