Oh, there'll be waiting lists. :(
The dealer who I've bought my past 2 Camaro's from has had a customer offer to place a $10K deposit for a new Camaro. The dealer refused ot of course as pricing has not been set yet.
My feeling is that once pricing is announced, as well as the models and the options, the lines will start forming.
I'll place my order and wait. But as Tag said, it will be well worth the wait.
