Trying to finally get my first Muscle Car - I’m nervous

I would stay away from the one you posted. I have been trying to get a former street/strip car back to being a good reliable driver for the last two summers. I have a lot of experience in automotive, been working on cars for close to 50 years now. It is never as simple as it would appear to be, there are always some things that need attention that you didn't expect to find or plan on. Paying someone else will get old really fast. Before very long you will have spent far more $$ than the car is worth when it comes time to sell it.
Like the other people who have responded have said, find the best car you can afford to buy, and learn about how it works and what you need to know about it to keep it and your family happy.
