Thanks for the input. I'll definitely take racalzo's advice and not blame the dealership for variances.
One thing that especially bothered me was the fact I was shown "all" of their available inventory. Then, as I drove away past their back-lot, I was pretty sure I saw a blue Escape. I just thought they might be holding back for some reason. That led me to check the online inventory, where it didn't list the blue one, but did list another one that I was not shown either (but thanks to timf I now know that "Dealer Ordered" means it wouldn't be there yet.) Perhaps the blue was one that was ordered by another customer and wasn't really in their inventory to sell? Regardless, I won't fret over it nor hold it against them.
