I have never figured the annual costs but I did just get new tags for my 66 and it was $225 but the plates are good for 5 years ( Antique vehicle ) and I don't have to get emissions. I use the "Cheaper than a car payment" argument all the time to justify the money I "Invest" in the Broncos. Usually this is true but not always. In 2012 I converted to a C4, put axles, ARB's, Family cage and reworked my engine bay. I also slipped in an order for new headers and 2 into 1 exhaust before the end of the year. If every year was like this one, it would be cheaper to own a new car! At least with the Bronco its probably not loosing any value, With my Expedition, it looses a little value every year.
