Do your research. Check Kelly Blue Book for the proper price for the vehicle, including its mileage and apparent condition. Always downgrade the condition by one ranking for government auctions. Also, do some smart used-car research, such as checking Consumer Reports for reliability and the frequencies of particular repairs, and checking our road test information if it's a recent model vehicle.
I wasn't aware that the TSA sold all of the stuff it confiscated! That's cheap goods right there! My mom works for a cruise line, and they don't confiscate stuff, but people do tend to forget all kinds of things they bring on the ship, so every once in a while the company has a big flea market available to employees. I find it funny when my mom comes home with watches and bracelets she wouldn't have otherwise bought.
