I have seen your TB/coin/car at the nice Geocoinfest Europe 2015 in Eindhoven, Netherlands.
Had a great time wandering through the event halls and parking garage, taking notes and knowing I would see my 10.000th trackable today :-)
Still counting, and probably will always have seen more trackables than geocaches :)
Friendly greetings from Woerden, Netherlands, and thank you for sharing!
