Shop around...there are a lot of 03's used for 24-28k. If he can hold out for a bit, there should be a ton of deals coming up on the remaining 04s that the dealers haven't/can't sell. Also, point him over to SVTPerformance.com and check out their version of the marketplace. A bunch of guys are dropping theirs so they can get a C6 vette...or whatever other lame excuse some of those guys have for trading/selling the greatest car to come along in a while.
EDIT: Some examples...even if they are not in state, it would be worth the extra couple hundred to have it delivered (I can give you the contact info for who I used to get mine down from NY), or a hell of a road trip.
03 Sonic Blue Coupe - 28k
03 Torch Red 10th Anniversary Vert - 31k
03 Mineral Grey Coupe with many mods (should be around 450 rwhp) - 26k negotiable
03 Sonic Blue Coupe with mods (418 rwhp before pulley and port) - 27.5k obo
There are more if you go through the list. So, this goes out to everyone really (This includes you StangGT804), if you are thinking about an 04-ish GT, check out the cobras you can pick up at a steal.
