Well I bought my red top Optima used for $50 about 2 years ago, it had been in a trail rig for about 3 years before that. Then I slapped it in my 4runner and since my yota is my DD I drive it pretty much every day (which seems to be the key to keeping optimas alive from what i gather). So far, I have:
left my head lights on for 5 days while on vacation, they were still on when I came back, not enough juice to fire it up but I bumped started it, charged it up and it was good to go
spent 7 hours of one day winching during a nasty extraction and it only killed my truck once
I put it in my boat only to find the boat has an electrical short or gremlin somewhere because it drained the optima twice while in the boat, had to get jumped twice.
and its still kicking. I have been really happy with my Optima. I have a few extra marine and deep cycle batteries laying around so when the Optima goes I will just use one of those but I have been extremely pleased with my red top.
