Bought a Wally world special to replace the original that lasted ten years in my Camaro ss.
When the pair of red top optima's went bad in the diesel pickup, I replaced them with interstates from Costco, $200 compared to over $500 for the two optimas. If they last half as long, I'm still ahead.
The box has almost new champions, available from pepboys among others, before they went belly up. Have had problems with them, turns out it's a drain from the other two batteries running the lift gate.
My Opel has HORRIBLE battery access, so it has an optima red top, five years old, going strong.
The 62 has an Interstate from Costco. I would have got the camaro battery from there, but they didn't have one when I needed it.
My go-to would be an interstate from Costco for almost anything.
