The most expensive car in Ford's lineup is the purebred, limited production, street-legal race car, the Ford GT. But the GT will never be able to tow your 35-foot cabin cruiser. The Super Duty Limited can easily do that while surrounding you in a luxurious interior that rivals anything else the Blue Oval brand makes. That gets you a 6.7-liter Power Stroke diesel, four-wheel drive, and your choice of single or dual rear wheels. Check every box on the options sheet and an F-450 Super Duty Limited will run you nearly $100,000. For a lighter load on your bank account and the street, the Limited package is also available on the F-150, -250, -350 models.
