to sell or keep

My '72 was my daily driver for a year about 15 years ago. It's lived in my garage since then - marriage, kids, jobs, etc. have made it a back-burner project for a long time. Yesterday I took the dead battery to the parts store, bought a new one, stuck it in and said "I know I shouldn't even try since it hasn't run in months, but what the hell?" Two tries and she started right up. That sound alone made it worth all these years of planning and waiting.
