I was just looking at cars today and came upon a 78 El Camino. They are selling it for a good price I can afford and the pictures look really nice. Its a V6, I don't need a V8. Will this car be easy to work on myself? Since it is a V6 will it get ok MPG? I mean my last car was a hand me down van that had a V6 and it got I'd say 20, will it equal that?
