>>11680438Even though they're scaled at 1:64, it's more like a general approximation-no 2 brands will end up with the same sizes and proportions when they try to make the same model car. They're mostly just trying to shrink the car down to a size where it fits in the same packaging as all their other car models.
Also, Matchbox and Hot Wheels never share castings, even for the exact same model cars. I found this out when I compared their renditions (along with Maisto) of the 2020 Corvette. The Matchbox is actually smaller than the Hot Wheels.
