Thank you for the reply and the helpful info. I never realized that the dealership could have issues a 90 day permit, I was under the impression that 30 is the max. The tag is issued on the same date of purchase by the dealer (30 days), they probably wanted to spare couple of dollars by issuing the 30 day one vs the 90 despite the ton of money that I paid them.
As for the hidden fees, not worried about them, just a rant and a heads up to others if they face such a dealership. Their charges were super hidden and sketchy. I probably caught most of them and thus reduced the price of the total out of pocket. Think of it as a Comcast bill with all the crazy hidden fees.
I have used the provided link and submitted a complaint, just not sure how effective and fast the General's office. Hopefully they are not understaffed. I really don't want to keep the car parked in my garage for 90 days. Good that I have another car to use, what about others that only have one car and purchased a car from them... Uber everyday till the Fields Infiniti dealership have mercy on them and work on the title and registration.
Indiana would send me temporary tags as soon as they get the title docs from the dealership, the problem is that they are not getting any docs from yet. The business office manager is sending them with errors and they return them back to him "twice" and of course he is taking his sweet time in doing things. If I made a mistake, I would throw everything I have on my hand to fix it, not ignore it and get to it when I have the mood.
Again, thank you for the link

, I used it and I also submitted a complaint via BBB. I wish if there was an entity that monitor and penalize dealer for such actions, like a dealer licensing agency or something similar.
