My Z is at Criswell Nissan in Germantown right now, getting new wheels put back on and all damage repaired from the wheel jacking incident last week. So far they've been nothing but courteous and upfront with me. Last year, I took my previous vehicle there (Sentra) which was out of powertrain warranty. The ECU had died, they replaced it for free, stating it was warranty work anyway. I didn't argue
So far only positive experiences with them.
