I did it for the first time yesterday ! I work in a single level office with around 300 other. The secure carpark is under the building. I was concerned that I might have dozens of car alarms going off when I drove in, but lucky only a few chirped their "warning" beeps....
Most heard it driving up the street, but I couldn't believe how many people commented that they felt the building shaking as I idled along under the building
I took one of my bosses for a drive, and I think I'm Employee Number 1 now !!! Everybody were great about the car being there. No jealousy or silliness, just a lot of people coming down to see what all the noise was !
It was a lot of fun to stand back and listen to comments from people that had no idea who owned the car. The owner of the car beside me felt embarrassed that every morning they wound up the windows, locked and immobilised their sedan while "that expensive sports car just sits there all open". She wound down her windows, unlocked her car, and walked away
