Monday around 7pm the PC area was mostly empty.
When I first got there, PC had a few minivans, a few SUVs (medium/large size), and one Toyota Camry. Five Star and Gold were a little better stocked, but mainly intermediates and maybe an occasional full size. The upgrade area had a few Merc's (didn't look close enough to see what models).
I lingered for a few minutes, and they drove a few more minivans and SUVs, into PC and then finally an Infiniti Q50 which I grabbed. Definitely worth the ~5 minutes I spent waiting...
