Breh I'm talking to you as a professional mechanic of 15 years, son of professional mechanic and owner of an antique car myself ('73 tbird):
Pros:
-You'll get that

from everybody, even in well to do areas, especially if you're young. My dad had a '63 bird, '67 dart, and a '57 dodge pickup, and I inherited the '73. These old cars, in good condition draw more looks than $100,000 cars.
-Rebuilding them is fun, you learn a lot, even if you don't do the work yourself, the people who do it for you will keep you updated and you'll learn a lot.
-You're a part of preserving history.
-You could luck up and have something that is worth a lot of money. I had a neighbor that had a '70 charger that sat on the street all through my childhood, and right when I was getting ready to graduate high school, he put it in his garage and started working on restoring it. Fast and the Furious just came out, and the value of those chargers skyrocketed. About five years later, I was one sell at the auction for $1 million.
Cons:
-This is the golden age of cars, the farther back you go, the worse they get, The reliability of older cars is vastly overstated, they need a lot of maintenance to keep them in the state you want them in.
-On that note, good luck finding parts.
_Keep your tools handy, older cars need a lot more maintenance than newer ones. People forget that back in the day, cars needed maintenance as few as every 15,000 miles, now we have cars that can go 15,000 miles on an oil change.
-If somebody hits it, you're gonna be sick.
