do you know why in mexico, they have a lot more models and makers than in the states?
It's the same around the world. Lots of vehicles that don't meet US Transportation Safety, Emissions, or fuel economy regs. are sold in foreign countries. Many are low quality and aren't worth the scrap value. Some are rebadged GM, Toyota, etc., made especially for foreign markets. It's just a different way of selling vehicles in different countries with less regulations than the US.
