Final check list before pulling trigger

[musert]

Hey everyone,
I was in an AD this evening and doing some last minute reconnoissance before pulling the trigger in the next month. This is my first visit to looking at an SS Submariner in person. Haven't really looked at the real thing in person. Seems smaller than I thought. I guess doesn't help I have been wearing a big face lately as daily watch. The sales guy didn't budge on any break in price($6000) if I paid cash. Was wondering if that's normal or because it's an AD they don't budge on price. Im located in Atlanta if anyone recommends or know someone would give me a break if I pay cash and is an AD would be great. Also, was wondering if anyone would recommend other dealers in Atlanta that sells preowned particularly 2008 M Series certified by Rolex if that exists and what price I should stay at. Any suggestions would be great. Thanks in advance!
