Full cash down payment? Ha! Tell that guy to fuck off. 1K, ok, that's reasonable for ordering a vehicle. That being said, they won't have any problem selling a Wrangler even if you walk away, so even that is really unnecessary.
Wait time depends on your location as well. I've ordered 2 and they both were ready for me to pick up inside 5 weeks from the day the dealer put the order in. I'm in Toledo so travel time was/is minimal. 6-8 weeks seems about right for other parts of the country.
So I guess you're calling him a dick for pointing out something dangerous, which kinda makes you a dick for calling him out and well holy fuck, it makes me a dick for calling you a dick.
