I just recently asked my LHS why the price difference, the kit was the new Mustang with the 007 branding, between the Euro issue, at an eye watering $60 dollars, and the same kit in the U.S. box at $29 dollars. She claimed it was because the Euro version came with paint and glue! I laughed, she laughed, the owner frowned!
Someone had just bought the ST Pizza Van in the Euro box for about $70!
