Got 6 years out of an AAP gold in our van.
The Mustang has one that is going on 5 years.
I replaced the OEM in the Accord with one, going from a size 51 to a 35 in '14.
In our van, I went with a Maxx from Wally World due to the fact that I bought it at 11PM on a Friday night and it was cheaper than another AAP Gold, even with the best discount code at the time.
They are a good battery and used to be a screaming value with the discounts.
Not so much the screaming value any more.
