I wonder if Matchbox and Hot Wheels are managed separately or are run from the same department. Because I really like the random Matchbox cars I find in the Dollar Tree far more than I do the Hot Wheels I find everywhere else. They're just so diverse in form.
Some research tells me that Tuk Tuks are popular in Thailand, where Matchbox cars are produced and this was a special collaboration between Matchbox and the Thai factory that makes the cars. They even had to create a new type of wheel.
