Talk to CamaroScotty or Eric Hall from this forum. You'll be able to get MSRP - Preferred Pricing - USAA discount. The Preferred Pricing is a % discount so it depends on your options. The USAA is $750 off the top.
I walked out with a 2SS with Polished Wheels ($480) for $33,500 + TTL.
You don't have to pay MSRP unless you just want to. There are deals and if you can wait about 4 mths there will be even better deals on 2010 when the 2011 start hitting the floor.
BTW: I'm not brand specific...although I personally don't like the changes they did to the new Mustangs at all. If the Camaro wouldn't have come out I was going to get a Shelby. I still like the looks of a nicely modded Mustang but the Camaro just makes me
. You need to get a test drive in an SS.
Here is a Mustang I lost out to about half a day to late. I would still have this one....not over the Camaro by any means but is was only $22k with 17k on it about a year ago.
