You don't have to pay for the Bronco when you order it. The 100 deposit is all you pay until it comes in and then if you don't like it for some reason your no obligated to purchase it. If your dealer is making you pay up front in the form of a larger deposit or the total cost of the Bronco you need to find another dealer .Wife and I talked over the weekend and we're waiting now. Between the possibility of other colors, the fact that I'll have to order and pay without likely ever getting to sit in and drive one (HUGE issue, I was at least lucky enough to see one in person), and a few other smaller issues - there is no downside to waiting, so we'll wait.
Best case - I find a used one with all the options and features I want and I might save some money. Worst case? They never add new colors or features and I order one the way I want anyways.
