GSAAuctions advice

Been looking at ways to get a super cheap car. GSAAUctions has some neat govt. fleet vehicles and other stuff for less than a thousand dollars on some.

Anything I should know about GSAAuctions? I'm pretty sure the govt. cars aren't criminal asset forfeiture, right?

If I were to successfully bid on something, what is the process on "getting it"? They issue you a certificate and you pay the final bid and go and grab it? Or is there something else I'm missing?

Never done this before...or bidding on anything at all. I hate bidding.
