We have the number 29 on the side indicating the extra day added to Febuary for the year 2016.
Leap year is on the front sides of the bonnet and the number of days 366 on the bonnet. On the roof is the name Matt Brutocao who is the senior marketing manager for Hot Wheels at the time.
All in all not a bad collectors piece and a bit of fun. Is this a rare piece? I do not think so as I have seen it in a lot of dump bins in my local area.
Happy Hunting and see you again soon
