Some do, some don't. My conversation was faster:
Me: Hi, I test drove one of your Zs a couple of months ago and want to buy the Brilliant Silver one you have on your lot. I'll give you $34,900 for it (sport, touring, splash guards, f+r mats, VIN etch).
Sales Manager: I can't sell it to you for that price.
Me: OK, no problem. Take care.
<10 seconds go by, my phone rings>
Sales Manager: OK, I'll sell it to you.
Me: Great! I'll be down in one hour with a check.
