Man, you would be totally amazed at the number of used cars going to Mexico every single day.I live on US Highway 59..the shortest route from Chicago to central Mexico at the Texas border. Every single day I see caravans consisting of usually a Mini Van pulling a small Suv, or a small suv pulling a small car...almost all are dented, wrecked and barely running,etc..Always Mexicans going south, I never see northbound traffic like that ..never and it is every single day...been like this for a few years.
