There is a new technological advancement that 12 engineers and 4 technicians to make. They are called Letrons and they are transforming cars. All Letron models are BMW cars. I think that these cars look like toys but the only thing interesting about them to me is that they are Transformers. Currently they do not have a walking function but with enough funding they will. These cars cost $600,000 but I think that they will soon cost more. A question I have is why the cars look like a Power Rangers toy?
