So, I will be the odd one here. I would buy one and hold on to it (a few cruise weekends here and there but no track).
My reason: I have a strong feeling that we are in a very short window of a muscle car renaissance. With the CAFE standards coming in a couple years and GM stating this is going to be a limited production run Camaro, this may be a car worth having a 4-5 years when the only thing you can get in a Camaro is a turbo 6cyl that looks like it belongs in a Toyota.
If the COPO would have been street legal (and they made a few more than 69 of them) I would have been in line for that for the same reason. Cars are most always a horrible investment but this one MIGHT be different.
