Mustang 1969 to 1970 Purchase advice

Hello together, I just wanted to ask you how it is about the mustang from 1969 to 1970. I like these models quite well, but it is mostly about the years before. A 1969 coupé is already to get for about 25 k€. Sure I will then also invest something (must) , only Should it still be kept within limits. But would I be interested, how does such a 1969/1970 Iger Mustang drive in contrast to a 1970 Camaro/Firebird? I wanted to nämlic? h originally once, only the selection is rather small and the prices are indeed astronomical in a good condition. What do you think the Mustang would be an alternative ? What I still notice, the Camaros/Firebirds standing on the net for a long time, sometimes over a year. Is the value possibly in the basement, respectively overrated. It would be nice if you could say something. Best regards Karl
