How long is the drive? See if one of the guys here or another one of your friends would drive one (or two if you need two cars driven) down in exchange for a few bucks, room/food, and a plane ticket back. Probably wouldn't be much more expensive (if any) than getting them shipped and you know they'd be careful with them.
