Well, it looks like steadily increasing numbers for car manufacturers might be taking a turn for the worse pretty soon. With new car sales increasing for the last seven years, the trend has to die sometime. With all of those brand new cars being sold and leased, it leaves plenty of fairly low mile vehicles in the dealership's hands. This is great news for car dealers and buyers, but it's very bad news for the car manufacturers.

With all of the cars that have been leased recently, plenty of newer, cheaper, low mileage vehicles will be at lots all around you. With car manufacturers like GM, Ford, and Fiat Chrysler experiencing a decline in sales, their share prices have remained fairly stagnant. With all of the money being dumped into autonomous driving technology, these companies need sales now more than ever, but they probably won't be getting much.

Since most people want their next big purchase to be an electric, self-driving machine, they're more likely to either not buy a car right now, or go the cheap route for the time being. That means less money will be getting into the hands of these car manufacturers and slower progression for autonomous driving capabilities. If you are invested in the Detroit Three at all, I would watch those share prices very closely for the time being. If you're currently looking for a car, this might be the best time to get something fantastic at a fairly low price!
