you just have to check out the dealerships.
i prefer stick to auto.
shelby might have put only sticks in as someone paying that kind of money would probably want a stick.
Yest most 2007 Shelby Cobras come stick. If you want to custome order one you can ask for it stick. Or hope somebody who custome ordered one is selling his/hers and you wont have to wait for your order to come in.
most coupe and GT mustangs are automatics.
Shelby mustangs are normally sold as stick.
However, my boss was able to get one modified to be an automatic.
