on my way home from work last night, all 4 were outside sitting in the parking lot. two blues, one white and i think 1 LG. it was pretty cool. wish i could have had time to stop and look close up and take pics. i did drive by again this morning and they were setup on display back inside, at least two that i could see. and yes, i've seen amazon vans on two different occasions inside the service center.What? 4? They had none early this week when I saw that prototype. Someone also reported seeing an Amazon van at the SC in Bellevue. I wonder if First Mile test drives will get scheduled soon here in WA!
