Is it ok? I was thinking of an Interstate Battery. The local tire shop I deal with sells them and says he has one for my E60. I asked about the vent tube and he says it has one. The price is half of what the stealrship wants. Should I do it?
I went with an optima blue top D34M

The best battery in the market!
