Bought a battery.... Porsche tax evaded.

[The French Dude]

It's not a secret dealers are very expensive on parts. I never buy parts from dealers.

Yeah, my friend works for Interstate Batteries, they just slap different stickers on the same battery, depending on which dealer they are going to, Porsche, Audi, etc.

Battery selection can start something here almost as big as oil and/or tire selection. As for me, I have an Interstate, and always will.
