Got mine this afternoon, so a little over 48hr ahead.

Was in the area and was unsuccessful fighting off my curiosity so I swung by North Houston to try take a peek. They were just finishing emptying 3 trucks. The back was jammed with vehicles, a line the entire length of the far side of the alley from Stripes until the turn-in to D&G Foods. The back of the building packed 3 bays down. There was +/- 70 cars, although a few were not 3's and some were clearly there for repairs (had aftermarket rims, plates, etc). They also had another eight new 3s in the alley along the North side of the build. I didn't check the closely at the 8-10 parked in the front of the building.
Also could see from outside that they had some inside, including mine since mine wasn't anywhere to be found in the lot.
P.S. One of the trucks was using an enclosed trailer and some rigging in there, like they use to ship your car along with your household goods for anyone that's ever had that done. I don't know exactly how many they could fit in there, though, because there was only one left in when I arrived. They also had the white jumpsuit on the lead, top vehicle of each of the open car carriers.
