^^^ true about it taking longer than 10 seconds. it is a PROJECT to add or remove the scion security. as for the dealer security system that some people (including us) put on the new cars to keep them from being stolen off the lot - that takes about 10 seconds to remove. our detail guys yank them when they wash and vac the new cars before delivery.
not true about where the system is added. i assure you, anything that i can add for my clients here at the dealer, i can have added to the cars at port. there is an assembly warehouse of sorts down in socal. its where your stickers and labels get added, and where, if we as dealers ask them to, they add any accessories. personally, we choose to have them install the stock deck, and floormats. we normally build the car at our dealer to suit the customer. but if a dealer says it came in that way, it very likely did. someone at their dealer had to tell the port to install it, though. so they screwed you in that respect.
