The 51 years difference allowed the 2016 version to reach 60 miles an hour from a standing start 3.1 seconds quicker and allowed a 51 mph higher top speed.

The 2016 version cost 14 times more and weighs 860 pounds more. In addition to inflation I suspect the additional weight accounts for a good share of the additional cost and that the weight is accounted for by safety regulations written by bureaucrats.

These "safety" regulations have more impact on us than cost, weight, and inconvenience. The "safety" regulations have stolen visibility. Think about it for a moment. How does reducing visibility while making cars faster make us safer? Cars used to have tremendous visibility, not only forward but rearward and on the sides. You could check your rear by looking over your left shoulder. You could check your right side with a glance to the right. This wonderful visibility was wiped out in the name of "safety."

First high-backed seats were mandated so you could no longer look over your left shoulder or your right. Next the side pillars were made massive so that you cannot even see anything on either side, and the front windscreen pillars were made massive so that if you turn left downhill you cannot see if there is anything in the road, such as a child, animal, or pothole. You cannot even see if a road is there.

As you can no longer see to the rear and to the sides the manufacturers use cameras. But unless you are young and learned to drive with cameras, you forget to use them. You are trying to look with your own eyes, and the "safety" bureaucrats have made it impossible. Use our artificial eyes they demand.

There was a time when only sport cars had seat belts. They were lap belts. Next sport cars moved to shoulder belts. This was prior to safety regulation. Sports cars had them because some drivers tended to drive the cars in a sporting manner.

"Safety" bureaucrats next mandated seat belts. Laws were passed to ticket you if you were caught driving without your belts. This was another new infraction that brought revenue to the state.

Next came airbags. At first they were deployed in front of the driver and front passenger. Today the airbags are also in the side doors and above your head. Consequently, what was once an inconsequential fender bender easily repaired at minor cost is now a total loss. The cost of fixing the car might be small, but the cost of replacing the multiple air bags is huge.
