Are prices way down on classic muscle right now?

From everything I've witnessed over the last 15 years, unless you're a mechanic or body guy or both, you won't get your money back on the car....sadly I'm neither.
There are a few cars where those rules don't apply...Corvettes up to 1972, E Bodies 70 to 72 and I guess Mustangs but I'm not familiar with that market. I'm sure I'm leaving out a few niche models but for the most part there are only a few. Now is a good time to, as they say, "buy as much car as you can afford" the deals are out there.
