A 70's Caddy would be a nice toy to have, but it's probably not a good idea to try to daily drive anything from the 70's these days unless you can tolerate breaking down. These cars are 40+ years old now, so everything that can go wrong - will go wrong.

The Cadillac family of engines from the 70s (472, 500, 425) were reliable. So you have nothing to be afraid of there. My question is why would you want to daily drive one the distances you mention? With the price of gas and the mileage those power plants get to the gallon, you will go broke.
