All too common with dealers now a days. I used to make my sales people call other dealers and act like customers and ask questions that they most often get. I'd do this on a speaker in my meeting room so that all my sales staff could hear how stupid the guys down the street are. In car sales you only have to be one notch above the worst guy on the block in order to look like a super star.
My advice is to GO to the dealer that is closest and most likely where you will service your car for warranty work. Walk in, bypass ANY and ALL sales people and go to the slaes manager. Be nice, stay calm and tell him you are a serious qualified buyer and that you have had problems with other dealers and you are sick of it and ready to buy. You will get his undivided attention. If he pawns you off to a sales person, walk out. Go to the next dealer.
This is my best advice being in the car business for the past decade in sales management. I would bend over backwards for people who only wanted to deal with the manager. Heck it got me out of the dealership, I took the customer on test drives and did the entire deal. If I closed the deal I looked like a hero/stud to my sales people and I'd put the unit up as a free car deal for good deed done or high CSI score ect. I'd get quit a few deals like this a month.
Good luck bro...
