Lamley Reader Muhammad Fadlul Fikri had himself an interesting find.
While perusing the pegs at his local Toys R Us in Malaysia, he came across this Hot Wheels Speed Graphics 5-pack. All looked the same except for the Toyota Supra:
Look closely and you will see it. The Toyota Supra on the left has Y5 wheels, while the Supra on the right has PR5 wheels. Y5 wheels is all I have seen so far, and this is the first I have seen of the PR5.
I have no idea if this is a running change that we will all see soon, or a rare variation. All I do know is I am keeping my eyes open for one.
