What are some cool 4-seater convertibles for 2011 and forth? And 50s to 70s muscle cars?

I'm talking Camaros, Mustangs, BMWs, etc. I really like American cars because they are affordable. But German cars like the BMW M3 and M6 are cool and unaffordable. What about the older 50s to 70s muscle cars? Like the Chevrolet Chevelle SS. Tell me about all those muscle cars and how much they cost if they are in good condition. Here is a list: Pontiac, Plymouth, etc.
