Your wife is a smart woman!
Waiting may be the smarter move. Besides being out of debt, you'll have more disposable income to use towards the new Camaro. I also prefer to wait about a year after a new cars introduction for two reasons; all the "bugs" are worked out, and you get a better idea of what models are available, (ie; "special" dealer models, etc.)
I understand your excitement. Once I see the new Camaro out on the streets, I'm going to have to practice patience, something I'm not always good at.
