It had to happen eventually. My silver Prius C is on the right with my son sitting inside. While I was taking the photos, the owners of the other one walked up to mine thinking it was theirs!
While at a friends house today, a gold Prius identical to mine drove by. They even stopped, pointed, and waved at us as we pointed and waved at them. I have seen like 3 different gold ones in my town since I bought mine.
