AC has always been an instigator and a reactionary company with poor service and shipping history. Jim joined their forum a long time ago and tried telling people about NPORA, the mods dissed him and put down NPORA without even giving him a chance, so he left.
I was a very active member of their forum (over 2000 posts, IIRC) until I wanted to talk about Calmini and L&P and other companies, at which point the mods AND Jane both told me to basically shut up and be a good little AC boy or else. I didn't shut up, so they banned me. After that one of the mods changed my profile to say "Child Molester". They even threatened me with legal action, which is pointless.
Point of the story is, don't buy from AC if you don't have to. They're worthless people and they only want to generate business for themselves, even at the expense of alienating other Nissan owners.
