Before 2013, all 12 "Treasure Hunt" cars of a year were released in both regular and super versions. In 2012, "Super Treasure Hunts" came with special paint and wheels, but with series designation on the card. However, the regular "T-hunts" retained a special "T-Hunt" series card. Mattel stopped using special cards for all "Treasure" "Hunts" in 2013. Some U.S. releases in 2014 had the phrase "This symbol on the vehicle lets you know it is hard to find and highly collectible".
