i've picked up 3 cars in IL, one in westmont, two in highland park. they don't come with metal plates, they come with the cardstock yellow temp plate. no car has had a front plate bracket installed, thank goodness, although they probably should have technically. i'd be suspicious of any metal plated "new" car.
i'd have refused that car, and i think you should return it. i refused my "reserved" LR AWD for reasons different from yours. after that, they (highland park) jumped and found what i wanted in an inventory car with 19 miles on it? iirc. they also discounted
i don't care about free supercharging, i charge at home and only take a road trip once or twice a year. non-issue, it's cheap anyway and there's plenty of free destination charges as well.
a wall charger is like someone giving you $400. If you don't want it, it's a quick flip for cash, someone wants it right now. you also had a color upgrade, that's pretty sweet too but not thaaat big a concession on their part.
at some point you have to be happy, figure out what that is and ask for it. be nice, be reasonable.
i've been dealing with tesla employees at the SC for a couple years, and the best approach is to not be angry. something about an upset customer destroys these millennials to the point of sensory overload. at that point, they tend to retreat and leave you crying in the parking lot. when i refused my car, the delivery gal grabbed a sales person and they joined me at the car. i explained to them, "nobody is upset here, you guys can find what I want, you have it. it's just not this one. take a look and give me a call" that seemed to empower them somehow, and 2 hours later (I left, ran some errands, they called me, i came back) i took delivery of my car. i couldn't be happier now.
the thing that really stabs people, is that your spending a lot of money and feel like your dealing with someone at an AT&T or Verizon store. well, welcome to the future. be glad "Idocracy" wasn't spot on. it could be so much worse. is it right? or acceptable? that's up to each and every buyer to decide on their own, and let the masses of reaction land where they may.
good luck, i know i just ranted a bit. i hope it doesn't come off as negative, highland park really came through for me in the end. i hope the SC you're working with does as well.
