whats everyone doing for car batteries these days??

You have an Opel? One of my first car times, after Dad passed. My Friend John Popp bought one for 5 bucks from a guy up the street. Think we were 15. Pushed it home by hand. Lol
Yep, a 69 gt. 454 in it for the time being. My best bud in high school had a Kadett. When he got done with it, it was a $10 car too.
