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

Thank you guys for all the advice! What would be the best place to get a loan for a classic car? Any suggestions?

Also, I was really set on getting one with a manual transmission, but someone on the forum has offered a really cool Plymouth Duster with an automatic transmission with a B&M shifter which I've never tried before. The pros of an automatic would mean I could let people I trust 100% take it for a spin (with me in the car of course haha). Most people I know don't drive manual. Besides, I'm having a hard time finding manual muscle cars for some reason. But people talk so much crap about the automatics I'm just not sure what to think.
You know you get the 4 speed so your friends can’t drive it and people won’t be able to steal it. What happens when your pals start spinning the tires and back the *** end into a ditch or mail box with your 50 year old car? As the other guys here have said, you can find nice dusters / dart sports for 10k and under and once in a while a really nice gem will show up. As noted, demons are rare, true H code 340 demons are even rarer now so you going to spend a really shiny coin for one and when you spend that kinda money, on a 50 year old car, you’ll not want to be driving it all the time cus of all the stupid drivers on the road and good luck finding a bank that will loan on a car of that age. Possible, but unlikely. And like the other guys said, get a car that you can learn on and drive that’s not a huge chunk of change so your not paying a shop 100 or so an hour to work on your car as that will add up very fast.
