I've been on the waiting list at both go my Rolex AD since the SS Pepsi was released years ago, with no love. But a re-seller/flipper guy that I've bought from before had a 2 month old Pepsi GMT in steel for $18,000. He was willing to take my 4yr old GMT II BLBR with a dinged 11 o'clock lug + my silver dial Yachtmaster (5 digit model) in trade + $500 cash back to me after he paid for shipping both ways.
Since I'd paid $9K out the door for the new BLNR 4 years ago with DavidSW.com, and $7000 for the used Yachtmaster (well, traded a $7K TT blue Sub for the YM, making the YM $7K), I thought it was a great deal. At the time (April 2019) I didn't know the value of a mint Gen 1 BLNR had climbed from $9K to $14-15K!
Otherwise, the best price I was seeing for buying the Pepsi was $17,500 at DavidSW.com for using bank wire transfer ($18,025 if using PayPal). And I would have had to sell my 2 watches on my own to buy this, and take the risk of being scammed. Only after I agreed to the deal with my watch guy did I get a cash offer for the two watches for $17,500 from a very reputable buyer who would wire me the money 1st and send me prepaid shipping labels, but then it was only enough money to get the DavidSW watch, while the 1st deal also was getting me $500 cash back.
The ding in my 11 o'clock lug was only about 0.3mm wide x 0.1mm deep, but I knew it affected the value (which later I found that LAWatchWorks could fix for a few hundred bucks). So, I received wholesale value for the 2 watches, and the guy who traded me probably profited $1,500 -$2000 due to me being afraid to get scammed.
A year ago one of my Rolex AD was remodeling and in a temporary location, so during an inventory liquidation they had a white gold pepsi GMT II for 35% off! After taxes their price was the same as one that DavidSW.com had for sale online. I figured that I could privately sell my BLNR, my Polar Explorer II, and my TT Blue Sub to pay for it if they would drop the price by 40% and I made the offer. I was going to put it all on a credit card right there and then, and pay it off by selling the three watches later. They were disinclined to acquiesce to my request.
